A failure criterion for brittle elastic materials under mixed-mode loading
The failure criterion of Leguillon at reentrant corners in brittle elastic materials (Leguillon 2002, Eur J Mech A/Solids 21: 61–72; Leguillon et al. (2003), Eur J Mech A—Solids 22(4): 509–524) validated in (Yosibash et al. 2004, Int J Fract 125(3–4): 307–333) for mode I loading is being extended to mixed mode loading and is being validated by experimental observations. We present an explicit d...
متن کاملProbabilistic Lexicographic Entailment under Variable-Strength Inheritance with Overriding
In previous work, I have presented approaches to nonmonotonic probabilistic reasoning, which is a probabilistic generalization of default reasoning from conditional knowledge bases. In this paper, I continue this exciting line of research. I present a new probabilistic generalization of Lehmann’s lexicographic entailment, called -entailment, which is parameterized through a value that describes...
متن کاملNonmonotonic probabilistic reasoning under variable-strength inheritance with overriding
We present new probabilistic generalizations of Pearl’s entailment in System [50, 32] and Lehmann’s lexicographic entailment [39], called and -entailment, which are parameterized through a value that describes the strength of the inheritance of purely probabilistic knowledge. In the special cases of and , the notions of and -entailment coincide with the probabilistic notions of and -entailment ...
متن کاملDynamic fragmentation of a brittle plate under biaxial loading: strength or toughness controlled?
The fragmentation of a brittle plate subjected to dynamic biaxial loading is investigated via numerical simulations. The aim is to extend our understanding of the dynamic processes affecting fragment size distributions. A scalable computational framework based on a hybrid cohesive zone model description of fracture and a discontinuous Galerkin formulation is employed. This enables large-scale s...
متن کاملFractal design for efficient brittle plates under gentle pressure loading.
We consider a plate made from an isotropic but brittle elastic material, which is used to span a rigid aperture, across which a small pressure difference is applied. The problem we address is to find the structure which uses the least amount of material without breaking. Under a simple set of physical approximations and for a certain region of the pressure-brittleness parameter space, we find t...
