From Brittle to Ductile Fracture in Disordered Materials [PDF]
, 2010 We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond

A thermodynamically consistent derivation of a frictional-damage cohesive-zone model with different mode i and mode II fracture energies [PDF]
, 2015 The present paper deals with the derivation of an interface model characterized by macroscopic fracture energies which are different in modes I and II, the macroscopic fracture energy being the total energy dissipated per unit of fracture area.

Influencing factors of conductivity of complex fractures in coalbed methane reservoir
Meikuang Anquan, 2022 Complex fracture network is easy to form after hydraulic fracturing in coalbed methane reservoir. In order to study the influencing factors of complex fracture conductivity, an improved proppant filling fracture conductivity tester was used to evaluate ...

STUDY ON DUCTILE FRACTURE CRITERION PARAMETERS OF HIGH STRENGTH DUPLEX STEEL PLATE
Jixie qiangdu, 2023 In order to predict the ductile fracture failure of different high-strength steel plates, the damage parameters of the ductile fracture criterion were calibrated by designing the tensile, shear and fracture failure tests of four high-strength steel ...

A Stochastic Bulk Damage Model Based on Mohr-Coulomb Failure Criterion for Dynamic Rock Fracture
Applied Sciences, 2019 We present a stochastic bulk damage model for rock fracture. The decomposition of strain or stress tensor to its negative and positive parts is often used to drive damage and evaluate the effective stress tensor. However, they typically fail to correctly

Understanding fast macroscale fracture from microcrack post mortem patterns [PDF]
, 2011 Dynamic crack propagation drives catastrophic solid failures. In many amorphous brittle materials, sufficiently fast crack growth involves small-scale, high-frequency microcracking damage localized near the crack tip.

Damage-cluster distributions and size effect on strength in compressive failure [PDF]
, 2012 We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local damage and reproduces the main features of compressive failure of brittle ...

Experimental methodology of study of damage initiation and development in textile composites in uniaxial tensile test [PDF]
, 2008 Damage in textile composites is closely connected with the internal micro- and meso-geometry of the reinforcement, and reveals features, which are not present in the damage processes in classical laminates. This paper proposes a test sequence intended to
