متن کاملStabilized and Block Approximate Inverse Preconditioners for Problems in Solid and Structural Mechanics
The solution of linear systems arising in the ®nite element analysis of shells and solids by the preconditioned conjugate gradient method is considered. Stabilized and block versions of the AINV factorized approximate inverse preconditioner are presented and tested on a variety of dicult problems. Comparisons with other preconditioning methods are also included.
متن کاملSolving Inverse Problems in Structural Damage Identification
Accurately identifying damage is difficult after an extreme event since damage often cannot be directly measured. Sensors, however, can collect data that reflects damage by measuring changes in structural response. Therefore, damage identification becomes an inverse problem in which the goal is to find system properties using limited response information. The inverse problem is formulated as an...
متن کاملInverse Problems and Optimal Control in Non Linear Mechanics
The purpose of this article is to present applications of optimal control theory in order to solve inverse problems in non linear mechanics. The constitutive equations of the material is known. In the first class of inverse problem, knowing the initial state and the final state of the body, we propose a method to estimate the history of loading and the internal state such as plastic strains kno...
متن کاملDamage Assessment using an Inverse Fracture Mechanics approach
This paper studies the application of an inverse methodology for problem solving in fracture mechanics using the finite element analysis. The method was applied to both detection of subsurface cracks and the study of propagating cracks. The procedure for detection of subsurface cracks uses a first order optimization analysis coupled with a penalty function to solve for the unknown geometric par...
