Abstract In this paper, two brittle fracture problems are numerically simulated: the failure of a ceramic ring under centrifugal loading and crack branching in PMMA strip. A three‐dimensional finite element package which cohesive elements dynamically inserted has been developed. The elements' strength is chosen to follow modified weakest link Weibull distribution. probability introducing weak set increase with size. This reflects physically based effect according larger more likely contain...
The mechanical performance of concrete is strongly influenced by the geometry and properties its components (namely aggregate, mortar, Interfacial Transitional Zone (ITZ)) from mesoscale viewpoint, analyzing material at that level should be a powerful tool for understanding macroscopic behavior. In this paper, simple highly efficient method proposed constructing realistic mesostructures concrete. A shrinking process based on 3D Voronoi tessellation was employed to generate aggregates with...
Dynamic damage evolution and its influence on the constitutive relation for materials in high strain rate are experimentally theoretically studied. It is revealed that a rate-dependent process depending both rate, can be modeled by thermo-activation mechanism. For polymer PMMA, PP/PA blend concrete, coupled law dependent (DM-ZWT model) obtained well supported experimental data.
One-dimensional impact response of graded cellular rods with monotonously increasing density distribution, which benefits in buffering the object proximal end, is investigated by using shock models and cell-based finite element models. Based on rigid–plastic hardening (R-PH) idealization, a theoretical model front propagation behavior subjected developed solved numerically fourth-order Runge–Kutta scheme. Finite analysis performed 2D random Voronoi technique, comparisons illustrate that...
