Parameter-based topology optimization for crashworthiness structures
Abstract Topology optimization methods like the homogenization method are very efficient for statically and dynamically loaded structures, but the use of these methods for the topology optimization of crashworthiness structures runs into a lot of problems. Especially in structural contact problems, the optimization functions are not smooth and the use of local sensitivity information is not suc...
متن کاملCrashworthiness Design Using Meta-models for Aprroximating the Response of Structural Members
Vehicle crashworthiness is an important yet difficult design attribute. It can be argued, that an assisting task for the design process would be to pre-compile library databases for the crash behavior of elementary structural members. Such databases would guide designers to quickly select the appropriate dimensions of structural members once estimates of the load requirements are available. Unf...
متن کاملDAMAGE IDENTIFICATION BY USING MODAL EXPANSION AND TOPOLOGY OPTIMIZATION IN THREE DIMENSIONAL ELASTICITY PROBLEMS
In this paper, topology optimization is utilized for damage detection in three dimensional elasticity problems. In addition, two mode expansion techniques are used to derive unknown modal data from measured data identified by installed sensors. Damages in the model are assumed as reduction of mass and stiffness in the discretized finite elements. The Solid Isotropic Material with Penalization (...
متن کاملTopology optimization using non-conforming finite elements: three-dimensional case
As in the case of two-dimensional topology design optimization, numerical instability problems similar to the formation of two-dimensional checkerboard patterns occur if the standard eight-node conforming brick element is used. Motivated by the recent success of the two-dimensional non-conforming elements in completely eliminating checkerboard patterns, we aim at investigating the performance o...
متن کاملA topology control algorithm for autonomous underwater robots in three-dimensional space using PSO
Recently, data collection from seabed by means of underwater wireless sensor networks (UWSN) has attracted considerable attention. Autonomous underwater vehicles (AUVs) are increasingly used as UWSNs in underwater missions. Events and environmental parameters in underwater regions have a stochastic nature. The target area must be covered by sensors to observe and report events. A ‘topology cont...
