Decoupling dislocation multiplication and velocity effects in metals at extreme strain rates
Daniyar Syrlybayev, Lavanya Raman, Niraj Pramod Atale +4
The dynamic behavior of metals is governed by collective dislocation motion and interactions that strongly depend on the applied strain rate. Metals exhibit weak strain rate sensit…
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…
