A Framework for Performing Multiscale Stochastic Progressive Failure Analysis of Composite Structures
A framework is presented that enables coupled multiscale analysis of composite structures. The recently developed, free, Finite Element Analysis – Micromechanics Analysis Code (FEAMAC) software couples the Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) with ABAQUS to perform micromechanics based FEA such that the nonlinear composite material response at each integration...
متن کاملA C Discontinuous Galerkin Formulation for Thin Shells
This paper presents a C discontinuous Galerkin formulation for the simulation of thin shells. The method is based on Koiter’s shell model and allows finite element solutions to be obtained by using standard C Lagrange basis functions in terms of the displacement only. It invokes a curvature-like term by applying a lifting operation which transforms jumps in the normal rotation across element bo...
متن کاملMultiscale Mechanics and Optimization of Gastropod Shells
A vast majority of mollusks grow a hard shell for protection. The structure of these shells comprises several levels of hierarchy that increase their strength and their resistance to natural threats. This article focuses on nacreous shells, which are composed of two distinct layers. The outer layer is made of calcite, which is a hard but brittle material, and the inner layer is made of nacre, a...
متن کاملIntroducing a New Formulation for the Warehouse Inventory Management Systems: with Two Stochastic Demand Patterns
This paper presents a new formulation for warehouse inventory management in a stochastic situation. The primary source of this formulation is derived from FP model, which has been proposed by Fletcher and Ponnambalam for reservoir management. The new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. Using this model, the expected value...
متن کاملAiaa 2000-1385 Bi-stable Composite Shells
This paper is concerned with a new type of deployable structures that can be rolled up like a tape measure but, unlike a tape measure, are stable in two different configurations. The key to the behaviour of these structures is a particular type of composite construction based on an anti-symmetric lay-up of glass fibres in a polypropylene matrix. The paper presents a finite element analysis usin...
