摘要
考虑材料的粘性效应及非线性外阻尼,建立了一类轴向载荷和横向载荷作用下具强阻尼非线性粘弹性简支梁方程;利用Faedo Galerkin法,证明了该方程解的存在唯一性。
We establish one kind of equations strongly demped nonlinear viscouselastic simply supported beam subjected to axial forces and transverse load, considering both viscosity effect and nonliear external damping, and obtain the existence and uniqueness theorem of global solutions for the equations by the FaedoGalerkin method.
