Research Abstract

In the present study, we developed topology optimization of composite structure to maximize the energy absorption capacity in terms of two different materials. The most significant point in the present study is the derivation of accurate sensitivity of the objective function with respect to the design variable.
We proposed the new approach capable of providing a highly accurate sensitivity by investigating the theoretical problems on other previous studies. The present method is considered as very efficient approach/method for the advance material design. The achievement is shown the two publication submitted to academic journal and six international/national congresses.
