Micro-mechanical finite element modeling of diagonal compression test for historical stone masonry structure

Jean-François Molinari, Katrin Beyer, Nicolas Richart, Shenghan Zhang, Seyedeh Mohadeseh Taheri Mousavi

Simulating the force-deformation behavior of stone masonry is a challenging issue. This paper contributes to this topic by developing a detailed micro-modeling method using extrinsic cohesive elements. To consider contact and friction, a new node-to-node a ...

Dynamic crack propagation in a heterogeneous ceramic microstructure, insights from a cohesive model

Seyedeh Mohadeseh Taheri Mousavi

Silicon nitride is a widely used industrial ceramic, specifically for dynamic loading applications because of its special mechanical and material properties. The investigation of the underlying mechanisms which lead to these properties is experimentally ch ...

Dynamic crack propagation in a heterogeneous ceramic microstructure, insights from a cohesive model

Jean-François Molinari, Nicolas Richart, Seyedeh Mohadeseh Taheri Mousavi, Cyprien Wolff

A 2D plane-strain dynamically propagating crack under tensile loading is simulated with cohesive elements. Information of the main crack is extracted from a diffuse crack network with the use of graph properties. Micro-transgranular fracture properties are ...

On the influence of transgranular and intergranular failure mechanisms during dynamic loading of silicon nitride

Jean-François Molinari, Seyedeh Mohadeseh Taheri Mousavi

Plane-strain tensile loading numerical simulations of dynamic crack propagation in silicon nitride microstructures are conducted. The strength and toughness are evaluated as a function of strain rate and microstructural parameters, including grain size and ...
