Unfortunately, this inevitably leads to many expensive simulations in terms of cost and time if an optimization or adaption of design parameters has to be done. In this work, a surrogate-assisted optimization algorithm is utilized to find the setting of design parameters, which would lead to maximum damage in a simple tensile testing scenario involving a notched specimen with as few FEM simulations as possible.","PeriodicalId":14601,"journal":{"name":"J.
