Enduring mechanical memory from the constitutive response of elastically recoverable nanostructured materials
Abhishek Gupta, Bhanugoban Maheswaran, Nicholas Jaegersberg +2
Mechanical memory and computing are gaining significant traction as means to augment traditional electronics for robust and energy efficient performance in extreme environments. Ho…
Implicit Geometric Descriptor-Enabled ANN Framework for a Unified Structure-Property Relationship in Architected Nanofibrous Materials
Bhanugoban Maheswaran, Komal Chawla, Abhishek Gupta +1
Hierarchically architected nanofibrous materials, such as the vertically aligned carbon nanotube (VACNT) foams, draw their exceptional mechanical properties from the interplay of n…
Embracing Nonlinearity and Geometry: A dimensional analysis guided design of shock absorbing materials
Abhishek Gupta, Komal Chawla, Ramathasan Thevamaran
Protective applications require energy-absorbing materials that are soft and compressible enough to absorb kinetic energy from impacts, yet stiff enough to bear crushing loads. Ach…
Dynamic Hardness Evolution in Metals from Impact Induced Gradient Dislocation Density
Jizhe Cai, Claire Griesbach, Savannah G. Ahnen +1
A clear understanding of the dynamic behavior of metals is critical for developing superior structural materials as well as for improving material processing techniques such as col…
Superior mechanical properties by exploiting size-effects and multiscale interactions in hierarchically architected foams
Komal Chawla, Abhishek Gupta, Abhijeet S. Bhardwaj +1
Protective applications in extreme environments demand thermally stable materials with superior modulus, strength, and specific energy absorption (SEA) at lightweight. However, the…
Origins of size effects in initially dislocation-free single-crystal metallic micro- and nanocubes
Claire Griesbach, Seog-Jin Jeon, David Funes Rojas +6
We report phenomenal yield strengths, up to one fourth of the theoretical strength of silver, recorded in microcompression testing of initially dislocation free silver micro and na…
