An analytic model of the evolution of dislocation density in fcc polycrystals is described. The
evolution equations approximately account for most known dislocation storage, dynamic …

The lack of comprehensive insight and accurate description on the dynamic
thermomechanical behaviors in high-temperature and high-strain-rate loading environment …

Semi-crystalline polymeric composites are increasingly used as bearing material in the
biomedical sector, mainly because of their specific mechanical properties and the new …

Using the shear-compression specimen (SCS), thermo-viscoplastic behavior of DP800 steel
has been investigated systematically over a wide range of strain rates, including quasi-static …

A dislocation density-based multiscale constitutive model is developed to describe the hot
deformation of high entropy alloys. The work hardening process of high entropy alloy is …

Hardening or softening associated with the increase of dislocation density is correlated with
strain rate and dislocation density. Taking aluminum as a model material, we investigate the …

The precision of traditional deformation resistance model is limited, which leads to the
inaccuracy of the existing rolling force model. In this paper, the back propagation (BP) neural …

High velocity transverse impact on reinforced composites is a matter of interest in the
automotive, aeronautical and biomedical sectors. Most existing studies have addressed this …

Multi-energy fields provide higher dimensional precision control and desirable performance
for microforming processes. The constitutive model under low strain level was established to …

In high-velocity forming process, material constitutive relationships are remarkably changed,
which has a significant effect on forming process and deformation behaviors. Based on the …
