Thickness effect study on the crushing characteristics of aluminum and composite tubes: Numerical analysis and multi-objective optimization

Since lightweight and energy-absorbing materials have an effective role in occupant safety during accidents, the use of aluminum or composite tubes and their optimum designs are of great importance in crashworthiness. In this study, numerical simulation of crushing and multi-objective optimization of aluminum and composite cylinders are performed to evaluate the effects of tube thickness on the objective functions (the specific energy absorption...
