由Gurtin变分原理求解一维动力响应的半解析法

The semi-analytical method derived by the authors based on Gurtin varia-tional principle to solve dynamic response 'akes finite element discretization in space domain and series in time domain. The numerical examples show that this method is effective for obtaining the solutions of dynamic response. The formulas of this paper can solve the dynamic response of one dimension with all kinds of initial conditions and all applied loads by introducing a kind of displacement function of nods.
