Modelování 2D anisotropního kontinua, aplikace na skladovací vaky

Abstract

The bachelor thesis deals with problems of modeling of fabrics in FEM. The deformation of the fabric under pressure is large and represents geometrical non-linearity. Modeling is the state of tension in memrane, deformation of the planar continuum and the total volume of the full bag. However, the membrane poses a problem in the first calculation step. Bending stiffness depends on the deformation of the membrane. In the initial geometric configuration, the membrane is flat and has zero stiffness. The mathematical solution doesn’t have the finite results. The work deals with finite-element model to eliminate this problem.
