In this contribution macroscopic modeling of phase transformations and mechanical behavior low alloy steels are developed investigated. Such is importance in simulations transient thermo-mechanical processes which can cause transformations, examples from the railway industry include train braking induced frictional heating as well rail grinding welding operations. We adopt a approach includes t...

The seismic behavior and plasticity spreading of a neotype column-slab high pier are researched in this paper. Four scale model tests of a web slab with two boundary columns are carried out under cyclic inelastic lateral displacements simulating seismic response. The test results show that the neotype column-slab high pier has strong and stable bearing capacity, good ductility, and energy dissi...

We investigate the cyclic behavior of laminate microstructures in finite-strain crystal plasticity and the resulting stress-strain response, based on a variational, incremental description of the microstructure evolution. The nonconvex free energy density in multiplicative singleand multi-slip plasticity gives rise to the formation of fine-scale deformation structures, experimentally observed a...

Background: Nickel-based superalloys are usually exposed to high static or cyclic loads in non-ambient environment, so a reliable prediction of their mechanical properties, especially plastic deformation, at elevated temperature is essential for improved damage-tolerance assessment of components. Methods: In this paper, plastic deformation in a single-crystal nickel-based superalloy CMSX4 at el...

The common approach to crystal-plasticity finite element modeling for load-bearing prediction of metallic structures involves the simulation simplified grain morphology and substructure detail. This paper details a methodology predicting structure–property effect as-manufactured microstructure, including true orientation, on cyclic plasticity, fatigue crack initiation in biomedical-grade CoCr a...

Theoretical and computational frameworks for synaptic plasticity and learning have a long and cherished history, with few parallels within the well-established literature for plasticity of voltage-gated ion channels. In this study, we derive rules for plasticity in the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, and assess the synergy between synaptic and HCN channel pla...
