چکیده
An ordinary state-based peridynamic (PD) shell model with arbitrary horizon domains is presented. In computations of the PD parameters, removes complete assumption when treating surface effect. this study, membrane, bending, and transverse shear deformations in framework are taken into account. To examine fracture mechanics behavior, crack opening displacements strain energy densities, which correspond to physical values failure criteria, investigated under single- mixed-mode conditions. Several numerical examples considered evaluate behaviors for structures subjected in-plane or out-of-plane loading. The effect near domain boundaries surfaces validly treated by using presented method. addition, a propagation analysis performed estimate effectiveness

متن کاملCiphers with Arbitrary Finite Domains
We explore the problem of enciphering members of a finite set M where k = |M| is arbitrary (in particular, it need not be a power of two). We want to achieve this goal starting from a block cipher (which requires a message space of size N = 2, for some n). We look at a few solutions to this problem, focusing on the case when M = [0, k − 1]. We see ciphers with arbitrary domains as a worthwhile ...
متن کاملProbabilistic Abstractions with Arbitrary Domains
Recent work by Hermanns et al. and Kattenbelt et al. has extended counterexample-guided abstraction refinement (CEGAR) to probabilistic programs. In these approaches, programs are abstracted into Markov Decision Processes (MDPs). Analysis of the MDPs allows to compute lower and upper bounds for the probability of reaching an error state. The bounds can be improved by refining the abstraction. T...
