研究了含脱层纤维金属层合梁的非线性动力响应问题。基于Repubshenko梁理论，考虑几何非线性、横向剪切变形、温度效应和接触效应，建立了非稳态温度场作用下纤维-金属层合梁的非线性运动控制方程，并采用微分求积法、Nermark-β法和迭代法求解。在算例中，详细讨论了脱层长度、脱层深度、温度场、几何非线性和横向剪切变形对含脱层玻璃钢层合梁非线性动力响应的影响。
The nonlinear dynamic response problems of fiber–metal laminated beams with delamination are studied in this paper. Basing on the Timoshenko beam theory, and considering geometric nonlinearity, transverse shear deformation, temperature effect and contact effect, the nonlinear governing equations of motion for fiber–metal laminated beams under unsteady temperature field are established, which are solved by the differential quadrature method, Nermark-βmethod and iterative method. In numerical examples, the effects of delamination length, delamination depth, temperature field, geometric nonlinearity and transverse shear deformation on the nonlinear dynamic response of the glass reinforced aluminum laminated beam with delamination are discussed in details.
