TL;DR: In this article, the authors used a multiquadric response surface (MRSM) and a radial basis function (RBF) for multiobjective optimization of a vehicle body in frontal collision.

TL;DR: In this article, molecular dynamics simulations were used to study deformation mechanisms during uniaxial tensile deformation of an amorphous polyethylene polymer, and the energy contributions from the united atom potential were calculated as a function of strain to help elucidate the inherent deformation mechanism within the elastic, yield, and strain hardening regions.

TL;DR: In this article, the role of constrained microplasticity around debonded particles or shrinkage pores in forming and growing microstructurally small fatigue cracks and is based on the cyclic crack tip displacement rather than linear elastic fracture mechanics stress intensity factor.

TL;DR: In this article, the effect of grain boundary energy and disorientation angle on the boundary sink strength was explored; the strongest correlation occurred between the grain boundary energies and the mean point defect formation energies.

TL;DR: In this paper, the authors examined size scale and strain rate effects on single-crystal face-centered cubic cubic (fcc) metals and found that dislocations nucleating at free surfaces are critical to causing micro-yield and macro-yielding in pristine material.
