本文研究了在热效应存在下,用Marguerre-Vlasov型非线性系统描述其弹性变形的动态薄扁壳。我们的主要结果是证明了整体存在性和唯一性的弱解的情况下,夹紧边界条件。唯一性的标准技术在这种情况下不直接起作用。我们利用Lasiecka最近的工作克服了这个困难(Appl Anal 4:1376-1422,1998)。
We study a dynamical thin shallow shell whose elastic deformations are described by a nonlinear system of Marguerre–Vlasov’s type under the presence of thermal effects. Our main result is the proof of a global existence and uniqueness of a weak solution in the case of clamped boundary conditions. Standard techniques for uniqueness do not work directly in this case. We overcame this difficulty using recent work due to Lasiecka (Appl Anal 4:1376–1422, 1998).
