Weakly non-linear creep of amorphous polymers near their glass transition, comparisons between models and experiment
Martin Roman-Faure, Zhaocheng Zhang, Catalin Picu +2
The non-linear mechanics of amorphous polymers near the glass transition reveals a stress-induced acceleration of stress relaxation of nanometric sub-units. Recent theoretical work…
On resolving meso-scale calculations of pore-collapse-generated hotspots in energetic crystals for consistency with atomistic models
Chukwudubem Okafor, Jacob Herrin, Catalin R. Picu +4
Meso-scale calculations of pore collapse and hotspot formation in energetic crystals provide closure models to macro-scale hydrocodes for predicting the shock sensitivity of energe…
A new open source framework for multiscale modeling of fibrous materials on heterogeneous supercomputers
Jacob Merson, Catalin Picu, Mark S. Shephard
This article presents MuMFiM, an open source application for multiscale modeling of fibrous materials on massively parallel computers. MuMFiM uses two scales to represent fibrous m…
Higher Order Continuum Wave Equation Calibrated on Lattice Dynamics
Zhijie Xu, R. C. Picu, J. Fish
The classical approach to linking lattice dynamics properties to continuum equations of motion, the "method of long waves," is extended to include higher order terms. The additiona…
Thermally Activated Motion of Dislocations in Fields of Obstacles: Effect of Obstacle Distribution
Zhijie Xu, Catalin Picu
The thermally activated motion of dislocations across fields of obstacles distributed at random and in a correlated manner, in separate models, is studied by means of computer simu…
