APPLICATION OF A SIMPLIFIED METHOD FOR THE DYNAMIC SIMULATION OF MULTILAYER PANELS

摘要

A new approach to the finite element simulation of the dynamic behavior of trimmed panels with an equivalent material is illustrated. By taking into account both the bending and membrane effects in a shell element, the proposed method overcomes the drawbacks of conventional methods, i.e., excessive calculation times and, in the case of software using equivalent shells, application limited solely to flat plates. Testing conducted on several finite element models of various complexities has validated the simplicity and reliability of the method.
