Hadi Eskandar,Ali Sadollah,Mojtaba Sheikhi Azqandi,Saeed Rahnama
Abstract
Laminate composite structures are employed in industries due to their exceptional stiffness-to-weight ratio and directional properties. Literature has investigated the pursuit of optimal designs for such structures. In this paper, water cycle algorithm (WCA) is utilized as a metaheuristic optimizer algorithm for single and multi-objective optimization problems. Design variables include the number of layers and the orientation angle of fibers within each layer. A comparative analysis is performed to evaluate the efficacy of the WCA in comparison to other well-established optimizers. The obtained optimization results yield valuable insights into laminated composite structures, affirming the applicability of the proposed methodology in composite structural design.
