A non-local continuum damage approach to model dynamic crack branching
Jean-François Molinari, Nicolas Richart, Cyprien Wolff
Dynamic crack branching instabilities in a brittle material are studied numerically by using a non-local damage model. PMMA is taken as our model brittle material. The simulated crack patterns, crack velocities and dissipated energies, compare favorably to ...
2015Dynamic 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 ...
Elsevier2015Specification of a micro-transgranular fracture parameter
Jean-François Molinari, Nicolas Richart, Seyedeh Mohadeseh Taheri Mousavi, Cyprien Wolff
The micro-transgranular fracture calibration with a help of an efficient parallel numerical tool is demonstrated in this poster. ...
2013Dynamic crack propagation in silicon nitride under tensile loading
Jean-François Molinari, Nicolas Richart, Seyedeh Mohadeseh Taheri Mousavi, Cyprien Wolff
In this presentation, we uncovered the physics behind the dynamic crack propagationin silicon nitride microstructures ...
2013Explicit non-local damage computations in dynamics: on the importance of the choice of the non-local variable.
Jean-François Molinari, Nicolas Richart, Cyprien Wolff
Traditional local approaches to continuum damage mechanics are known to lead to mesh dependency due to damage localization. Some corrections for this ill-posed problem exist through localization limiters. The integral non-local regularization is widely use ...
