A compliance based design problem of structures under multiple load cases
There are two popular methods concerning the optimal design of structures. The first is the minimization of the volume of the structure under stress constraints. The second is the minimization of the compliance for a given volume. For multiple load cases an arising issue is which energy quantity should be the objective function. Regarding the sizing optimization EPSRC grant EP/E004547/1. A. Mak...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Compliance optimization of a continuum with bimodulus material under multiple load cases
Topology optimization of a continuum with bimodulus material under multiple load cases (MLC) is investigated by using material replacement method. Using traditional methods to solve such a problem will encounter two difficulties for the sake of the stress-dependent behavior of bimodulus material. One is the nonlinear behavior of bimodulus material. The other is the definition of local material ...
متن کاملOptimal Design of Geometrically Nonlinear Structures Under a Stability Constraint
This paper suggests an optimization-based methodology for the design of minimum weight structures with kinematic nonlinear behavior. Attention is focused on three-dimensional reticulated structures idealized with beam elements under proportional static loadings. The algorithm used for optimization is based on a classical optimality criterion approach using an active-set strategy for extreme lim...
متن کاملTopological Derivative-based Topology Optimization of Structures Subject to Multiple Load-cases
The topological derivative measures the sensitivity of a shape functional with respect to an infinitesimal singular domain perturbation, such as the insertion of holes, inclusions or source-terms. The topological derivative has been successfully applied in obtaining the optimal topology for a large class of physics and engineering problems. In this paper the topological derivative is applied in...
