Molecular dynamics (MD) shows a difference in the mechanisms of fracture of iron under
uniaxial and isotropic tension. Uniaxial tension leads to the formation of a complex …

We compare two machine-learning-based approaches, artificial neural network (ANN) and
micromechanical model with automatic Bayesian identification of the model parameters, in …

We develop the theory of homogeneous nucleation of dislocations, which predicts plasticity
incipience in FCC single crystal using material properties at elastic stage. In contrast to …

Numerous studies have investigated the strain rate sensitive behaviors of materials,
consistently reporting enhanced stress values and increased dislocation density with rising …

A micromechanical model of metal powder compaction is developed as a generalization of
the previous model proposed by Mayer et al.(2020). The model is applicable for an arbitrary …

Molecular dynamics (MD) simulations explored the deformation behavior of copper single
crystal under various axisymmetric loading paths. The obtained MD dataset was used for the …

In this study, we formulate a mechanical model of spall fracture of copper, which describes
both solid and molten states. The model is verified, and its parameters are found based on …

Dynamic tensile (spall) fracture of pure Pb and Sn in solid and molten states is investigated
by MD simulations. The influence of unwettable inclusions on the spall strength is revealed …

Taylor impact tests involving the collision of a cylindrical sample with an anvil are widely
used to study the dynamic properties of materials and to test numerical methods. We apply a …

Elastic–plastic waves of shock compression and unloading in annealed AD1 aluminum
were recorded at room temperature, 508 C, and 610 C. Using measurements of the …
