Ironclad diabolical beetles have a puzzling ability to withstand the pressure of being run over by a car without getting squished. 614-890-4700, Copyright 2018 - The American Ceramic Society, Tough beetles reveal secrets that could help join dissimilar materials, President’s Council of Student Advisors (PCSA), Subscribe to the Ceramic & Glass Manufacturing Weekly newsletter, Progress in Ceramics Series: Additive Manufacturing of Ceramics, Progress in Ceramics Series: Refractory Ceramics, Progress in Ceramics Series: Sintering of Ceramics, Functional Glass Manufacturing Innovation Consortium, Introduction to Ceramic Science, Technology, and Manufacturing, Statistical Process Control in Ceramic Processing, Record Retention/Document Destruction Policy, Jesus Rivera; University of California, Irvine, Toughening mechanisms of the elytra of the diabolical ironclad beetle, Hybrid SmartMat@2020 welcomes virtual and in-person participants to Thailand, Lifting the veil on record efficiency: Researchers detail how they created record-setting perovskite/silicon tandem solar cell, Video: Clay tiles help restore coral reefs, Other materials stories that may be of interest, Asking big questions of a microscopic particle: Scientists probe secrets of ancient mummy painting. This structure also incorporates a unique layered microstructure that prevents localized stresses, another way the beetle strategically dissipates energy to resist crushing. They also note that tuning material parameters could further enhance these structures, providing exciting possibilities for robust new strategies to engineer structures as tough as diabolical beetles. 3:10 . Stress concentrates around the perimeter of the insect’s shell, so these structures provide critical support precisely where it’s needed most. I recorded this video in Paige, Texas (Bastrop County) on June 11, 2016 at 19:48. Scientists developing new materials are studying an unlikely source of strength: The diabolical ironclad beetle, which can withstand being run over by a car. The paper, published in Nature, is “Toughening mechanisms of the elytra of the diabolical ironclad beetle” (DOI: 10.1038/s41586-020-2813-8). The diabolical ironclad beetle can take on an applied force of about 150 newtons, researchers say. In addition to having adapted rather well to life on earth, one of the secrets to the success of beetles seems to be that these kind of insects don’t often go extinct. For instance, the scientists note that such information could be used to design more robust strategies to join different materials, which remains an engineering challenge in aerospace applications and beyond. The diabolical ironclad beetle can withstand forces up to 39,000 times its body weight. Such materials are currently joined by mechanical fastening, which adds weight and introduces stress concentrators that degrade the strength and can lead to fatigue issues, corrosion and early failure,” the authors write in the paper. This strategy of varying stiffness increases the exoskeleton’s toughness by not simply allowing it to withstand pressure—it also strategically deflects energy away from critical areas, like where the internal organs are located, to other areas of the exoskeleton that can better dissipate energy without catastrophic failure to the beetle. “That’s its adaptation,” said David Kisailus, who was the principal investigator on the project. A new study reveals some of the secrets the beetle stores in its tough exoskeleton, secrets that could develop biomimetic materials and structures to join dissimilar materials in more robust ways. Entomologists know that the beetle’s exoskeleton is so tough that it can bend the steel pins used to mount specimens of insects for display. Researchers at the University of California, Irvine and other institutions, revealed the secret to the diabolical ironclad beetle’s near indestructible nature in a scientific paper published in Nature on October 21.The beetle’s “crush-resistant” exoskeleton, specifically its elytra, allow it to withstand up to 39,000 times its body weight, the University said. And the insect can even get up and walk away unharmed after being run over by an automobile—see for yourself below. Insights into what makes the diabolical ironclad beetle so strong could lead to the development of new materials with the same toughness, a new study has suggested. Sun TV. But what makes this little beetle so diabolically tough? 3:10. Supports further back along the shell don’t interlock but rather feature a latching design, while supports still further toward the back of the insect’s shell are entirely free-standing and feature no mechanical connection. The Nosoderma diabolicum, also known as the diabolical ironclad beetle is known for its durability. The team—an international group of scientists from University of California Riverside, University of California Irvine, Purdue University, University of Texas at San Antonio, Tokyo University of Agriculture and Technology, and Lawrence Berkeley National Laboratory—used advanced microscopy and spectroscopy to reveal that a mixture of macrostructure and microstructure elements combine to make the diabolical ironclad beetle’s exoskeleton incredibly strong. This beetle is nearly indestructible. The findings could help engineers create hardier vehicles and planes. These tests showed that the beetle-based structures were slightly stronger but exhibited significantly increased energy displacement to avoid catastrophic failure compared to commercial aerospace fasteners. The diabolical ironclad beetle (PA) Pablo Zavattieri, Purdue’s Jerry M and Lynda T Engelhardt professor of civil engineering, said: ‘The suture kind of acts like a jigsaw puzzle. The team specifically focused on a part of the insect’s exoskeleton called the elytra, which are two hard, protective blades that armor a beetle’s back to protect a set of more delicate wings used for flying. This architecture binds the elytra together, providing support at an otherwise weak location of a joint in the exoskeleton. … 866-721-3322 or This ‘diabolical’ beetle can survive being run over by a car. — Getting run over by a car is not a near-death experience for the diabolical ironclad beetle. The findings, which help to explain the beetle’s ability to survive huge crushing forces, may have applications in construction and engineering fields such as aeronautics, researchers say. The American Ceramic Society The findings could help engineers create hardier vehicles and planes. In 2015, when entomologists told Jesus Rivera that a beetle found primarily on the west coast of North America had this “superpower” that allowed it to survive being run over by a car, he didn’t believe them. To confirm that these various scales of structure and architecture account for the beetle’s toughness, Kisailus and the team mimicked the beetle’s ironclad structures in 3D-printed composite fasteners and tested their mechanical strength in the lab. “These designs could be useful in joining other dissimilar engineering materials such as plastics and metals. Basically, there isn’t a shoe on Earth that can kill the diabolical ironclad beetle. The diabolical ironclad beetle can survive getting run over by a car. The ‘diabolical ironclad beetle’ can withstand enormous crushing force more than 39,000 times its own body weight, enough to survive being run over by a car. Yet while all beetles seem to be a bit stubborn in terms of survival, there is one particular species of beetle that stands out for taking its toughness to an entirely different level—the diabolical ironclad beetle, Phloeodes diabolicus. [Image above] The diabolical ironclad beetle is tough—in addition to the ability to play dead and a rough exoskeleton that resembles a rock, this little beetle is hiding some interesting secrets within its exoskeleton that could help design more robust fasteners.
