We report molecular dynamics simulations of shear in a biomimetic hydroxyapatite-collagen composite. Our model exhibits elastic properties fully dominated by the inorganic component. However, beyond the elastic regime the biomolecules along with the hierarchical nature of the composite account for the formation of structure-inherent slip zones. These accommodate shear without compromising the o...

A continuum theory for high temperature creep of polycrystalline solids is developed. It includes the relevant deformation mechanisms for diffusional and dislocation creep: elasticity with eigenstrains resulting from vacancy diffusion, dislocation climb and glide, and the lattice growth/loss at the boundaries enabled by diffusion. All the deformation mechanisms are described with respect to the...

This contribution presents an asymptotic formulation for the stick-slip behaviour of incomplete contacts under oscillatory variation normal load, moment, shear load and differential bulk tension. The description allows us not only to approximate size slip zones during steady-state a cyclic problem without knowledge geometry or contact law, but provides solution when all known analytical solutio...

Bondstress-slip models of externally bonded FRP plates have long been quantified using push/pull shear tests in which the joint is slightly greater than effective length plate. This inhibits formation a frictional component that may arise joints. Moreover, previous researchers used several factors to represent bondstress-slip model parameters gave rise number models. With mind, first aim this s...

[1] A mismatch of elastic properties across a fault induces normal stress changes during spatially nonuniform in-plane slip. Recently, Rudnicki and Rice showed that similar effects follow from a mismatch of poroelastic properties (e.g., permeability) within fluid-saturated fringes of damaged material along the fault walls; in this case, it is pore pressure on the slip plane and hence effective ...

Thermodynamically consistent, three-dimensional (3D) phase field approach (PFA) for coupled multivariant martensitic transformations (PTs), including cyclic PTs, variant– variant transformations (i.e., twinning), and dislocation evolution is developed at large strains. One of our key points is in the justification of the multiplicative decomposition of the deformation gradient into elastic, tra...

How fold and thrust belts (FTBs) evolve over time space in a transpressional regime remains poorly understood. Based on high-resolution 3D seismic reflection data remote sensing images, we herein present detailed structural analysis of the Cenozoic faults NW margin Qaidam Basin that is bounded to north by left-reverse Altyn Tagh fault system. Two sets orthogonal, basement-involved with contrast...
