Abstract
An optimization method has been presented to simultaneously identify the bird’s constitutive model and its parameters automatically in the bird strike problems. The full contact‐impact coupling algorithm of finite element method (FEM) has been applied and the optimization objective is to minimize the square sum of percentage errors between testing results and FEM results. As an example, two bird’s material constitutive models, Plastic Kinematics model and hyper elastic Mooney‐Rivlin Rubber material model, have been used to testify the feasibility and reliability of the optimization method. The results show that the method presented in this paper can be used to study the bird strike problems.
