Finite Element Stress Extraction by the Complementary Energy Principle
This paper presents a new method for accurate pointwise stress extraction from nite element solutions, applied to two-dimensional linear elastostatic problems having bounded value stresses. The method, denoted by SEC (Stress Extraction by Complementary principle), is based on the complementary energy principle applied over a local domain in the post-processing phase. Detailed formulation of the...
متن کاملPure Complementary Energy Principle and Triality Theory in Finite Elasticity
It is well-known that the complementary energy principle for large deformation elasticity was first proposed by Hellinger in 1914. Since Reissner clarified the boundary conditions in 1953, the complementary energy principles and methods in finite deformation mechanics have been studied extensively during the last forty years (cf. e.g. Koiter, 1976; Nemat-Nasser, 1977; Atluri, 1980; Lee & Shield...
متن کاملA note on revelation principle from an energy perspective
The revelation principle has been known in the economics society for decades. In this paper, I will investigate it from an energy perspective, i.e., considering the energy consumed by agents and the designer in participating a mechanism. JEL codes: D7
متن کاملA free energy principle for the brain.
By formulating Helmholtz's ideas about perception, in terms of modern-day theories, one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts: using constructs from statistical physics, the problems of inferring the causes of sensory input and learning the causal structure of their generation can be resolved using exactly the same p...
متن کاملA Free Energy Principle for Biological Systems
This paper describes a free energy principle that tries to explain the ability of biological systems to resist a natural tendency to disorder. It appeals to circular causality of the sort found in synergetic formulations of self-organization (e.g., the slaving principle) and models of coupled dynamical systems, using nonlinear Fokker Planck equations. Here, circular causality is induced by sepa...
