Abstract: To understand and model damage generated during impact by a penetrator of ultrahigh strength concrete targets, edge-on impact tests are performed with Ductal concrete, which is unreinforced or reinforced with short fibers. ...

Abstract: In structures containing brittle materials, residual and/or heterogenous stresses may prevent cracks to propagate up to failure. Consequently, for such structures, crack arrest has to be accounted ...

Abstract: Failure conditions are assessed when ceramics exhibit Subcritical Crack Growth from preexisting flaws. In the framework of the weakest link theory and independent events hypothesis, a reliability ...

Abstract: Crimped mineral wools are characterized by a strongly anisotropic microstructure, whose local preferential orientation is highly heterogeneous. It is proposed to identify the local anisotropic ...

Abstract: Characterization of the tensile behavior of unreinforced and fiber-reinforced cement and concrete is delicate because of strain localization, which introduces a strong heterogeneity of the strain throughout the specimen ...

Abstract: The ultimate strength of structures made of brittle materials—such as microconcrete—strongly depends on microstructural defects, the structure size, and the loading pattern. Probabilistic approaches allow one to take account ...
