A damage mechanics model for quasi brittle materials based on the structured deformation theory
M. L. M. François
The structured deformation theory is used within the thermodynamics of irreversible processes framework in order to build a damage model relevant for quasi-brittle materials. The c…
Virtual Image Correlation uncertainty
M. L. M. François
The Virtual Image Correlation method applies for the measurement of silhouettes boundaries with sub-pixel precision. It consists in a correlation between the image of interest and…
A new yield criterion for the concrete materials
Marc Louis Maurice François
The proposed yield criterion depends upon two material constants and is proven to be smooth and convex under a simple condition. These properties induce a mathematical robustness t…
A damage model with non-convex free energy for quasi-brittle materials
Marc Louis Maurice François
A state coupling between the hydrostatic (volumetric) and deviatoric parts of the free energy is introduced in a damage mechanics model relevant for the quasi-brittle materials. It…
