Optimization of engineering structures by heuristic algorithms

In this paper, we present a new hybrid method of optimization by the heuristics algorithms to evaluate the reliability of the electronic card by simulating its thermo-mechanical behavior. A model of simulation by finite element is developed to consider the maximal deformations due to the temperature; a mechanico-computing coupling is used to find the optimal structure. Embedded electronic systems are playing a very important role in several areas, such as in automotive, aerospace, telecommunications and medical sectors. To properly perform their functions, electronic systems must be reliable [8]. This powerful and robust algorithm which is based on hybridization of Differential evolutionary algorithm with Particle swarm optimization gives performance results [7].
