Abstract This study sought to use the stress–strain relationship of interlocking stabilized soil block (ISSB) masonry model its behaviour and develop empirical formulae aid in predicting compressive strength. A finite element (FE) analysis adopting Rankine failure criterion was performed using Abaqus software simulate deformability wall which validated through experimental tests. The strength, ...

Abstract In this paper, a framework for the simulation of crack propagation in brittle and ductile materials is proposed. The derived by extending eigenerosion approach Pandolfi Ortiz (Int J Numer Methods Eng 92(8):694–714, 2012. 10.1002/nme.4352 ) to finite strains connecting it with generalized energy-based, Griffith-type failure criterion fracture. To model elasto-plastic response, classical...

In this paper, an industrially-oriented two-scale approach is provided to model the drop-induced brittle failure of polysilicon MEMS sensors. The two length-scales here investigated are the package (macroscopic) and the sensor (mesoscopic) ones. Issues related to the polysilicon morphology at the micro-scale are disregarded; an upscaled homogenized constitutive law, able to describe the brittle...

The problem of dynamic symmetric branching of a tensile crack propagating in a brittle material is studied within Linear Elastic Fracture Mechanics theory. The Griffith energy criterion and the principle of local symmetry provide necessary conditions for the onset of dynamic branching instability and for the subsequent paths of the branches. The theory predicts a critical velocity for branching...

Structural design with brittle materials requires that the stress level in the component correspond to a material survival probabi 1 i ty that exceeds the minimum survival probability permitted in that application. This can be achieved by developing failure models that fully account for the probability of fracture from defects within the material (including considerations of fracture statistics...

The experimentally determined marked rise of the stress intensity factor required to initiate crack propagation in brittle solids under variably high loading rates, is analyzed. This problem of fracture initiation at the tip of a crack is considered in terms of activating a flaw at some distance away from the tip. By using a semi-infinite crack in an unbounded two-dimensional solid subjected to...

In this paper, a compression-to-tensile load converter device is developed to determine the anisotropic tensile strength of brittle material. A cubic sample with an internal pore was used as the test specimen, and a series of finite element analysis and DDM simulations were performed thereafter to analyse the effect of pore dimensions on the stress concentration, as well as to render a suitable...
