Topology optimization of nonlinear structures
In this paper, topology optimization of both geometrically and materially nonlinear structure is studied using a general displacement functional as the objective function. In order to consider large deformation, e2ective stress and strain are expressed in terms of 2nd Piolar–Kirchho2 stress tensor and Green–Lagrange strain tensor, and constitutive equation is derived from the relation between t...
متن کاملTopology optimization of hyperelastic bodies including non-zero prescribed displacements
Stiffness topology optimization is usually based on a state problem of linear elasticity, and there seems to be little discussion on what is the limit for such a small rotation-displacement assumption. We show that even for gross rotations that are in all practical aspects small (< 3 deg), topology optimization based on a large deformation theory might generate different design concepts compare...
متن کاملSTRUCTURAL DAMAGE DETECTION BY USING TOPOLOGY OPTIMIZATION FOR PLANE STRESS PROBLEMS
This paper aims to introduce topology optimization as a robust tool for damage detection in plane stress structures. Two objective functions based on natural frequencies and shape modes of the structure are defined to minimize discrepancy between dynamic specifications of the real damaged structure and the updating model. Damage area is assumed as a porous material where amount of porosity sign...
متن کاملTopology optimization of periodic microstructure of electromagnetic material
1 Abstract This paper describes a topology optimization method for structures in electromagnetic materials. The material structures that exhibit special characteristics in terms of the repulsion of electromagnetic waves tend to be configured as periodical composite structures built of two or more materials. Generally termed “metamaterials”, these sometimes have especially unusual or even counte...
متن کاملStress and fatigue constrained topology optimization
This thesis concerns structural optimization in conceptual design stages, for which constraints that are adapted to industrial requirements have been developed for topology optimization problems. The objective of the project has been to identify and solve problems that today prevent structural optimization from being used in a broader sense in the avionic industry; the main focus has been on st...
