 Design optimization for a simulation of rotating anisotropic viscoelastic porous structures using time-domain OQBEMMohamed Abdelsabour Fahmy Mathematics and Computers in Simulation (MATCOM), 2019, vol. 166, issue C, 193-205 Abstract: The main purpose of this paper is to propose a novel efficient design optimization technique based on the operational quadrature boundary element method (OQBEM) for a simulation study on the material distribution and influence of rotation on the optimal design of rotating anisotropic viscoelastic porous permeable structures. An implicit differentiation method was developed to calculate the design sensitivities of displacements and pore pressure with respect to design variables and the effects of rotation on these sensitivities are also discussed. The optimization problem is solved using the Moving Asymptotes Method (MAM) which requires the calculation of the sensitivities for objective function and constraints by adjoint variable method. The optimum shape design of an elliptical sandwich structure is used as the numerical example to verify the validity and accuracy of the proposed technique.
