Wrinkle Generation Mechanism without Buckling in Sheared Rectangular Membrane
説明
The objective of this study is to clarify wrinkle generation in membranes. It is generally considered that wrinkles are generated by local buckling. The bifurcation buckling is a singular point in numerical computation and the post-buckling solution is difficult to calculate. Types of buckling can be predicted in advance by asymptotic theory. Thus, we introduce a path analysis method into the finite element software package ABAQUS. This analysis uses eigenvectors corresponding to the zero eigenvalues of the tangent stiffness matrix in order to calculate the post-buckling equilibrium path. Using this method, we calculate wrinkle generation in a rectangular membrane. As the result, this study shows a novel wrinkle generation mechanism without buckling and clarifies the bifurcation structure of the system.
