In this investigation, a combined experimental and computational approach with a Modified Mohr Coulomb (MMC) fracture criterion employing post-initiation element softening is used to simulate stable crack propagation under Mode I, Mode III and combined Mode I/III loading conditions. Results from the studies demonstrate that good correlation exists between the measured load-displacement and the ...

In this investigation, the three-parameter Modified Mohr–Coulomb (MMC) fracture model and the determination of the material parameters are briefly described. The formulation of the post-initiation behavior is proposed by defining both the explicit softening law and the incremental damage evolution law. As opposed to the existing attempts to simulate slant fracture with material weakening before...

Abstract Mortar in masonry structures can be subjected to both uniaxial and triaxial loading. Determining the mechanical properties and/or failure criteria of commonly used mortar is necessary for structural performance assessment new existing buildings using non-destructive testing finite element modelling methods. In this paper, stress–strain behaviour a commercially available cement-lime inv...

This paper presents an experimental study to analyse the bonding strength between geopolymer concrete (GC) and normal (NC) bond substrate. Three different strengths of GC which were 80 MPa, 85 MPa 90 bonded 30 NC denoted asNC30-GC80, NC30-GC85 NC30-GC90. Slant shear split tensile tests conducted investigate two substrates. The effect was then determined by using Mohr-Coulomb theory where critic...
