DOI: 10.1016/j.ijmecsci.2019.03.010
Abstract: Abstract Cyclic softening behavior at elevated temperature of nanolath strengthened steel was rationalized under different strain amplitudes. Results indicated that the evolution of internal stress components and the coarsening of subgrains are significantly depending on… read more here.

DOI: 10.1063/5.0045131
Abstract: We present a dislocation-based strength model for tantalum that captures the plastic deformation at high strain rates above 10 3 s − 1. The model has its origins in molecular dynamic simulations and it is… read more here.
