Sažetak
Non-linear numerical analysis of deformation and stress of a flexible material (textile, leather, thin foils) in plane stress is done using the finite element method .The material non-linearity related to a reduced carrying capacity in compression is modelled by a low constant compressive stress limit. The final state satisfying both equilibrium conditions and material non-linearity is obtained by an iterative procedure similar to the one applied in computational plasticity. A home developed algorithm based on triangular finite elements and Gauss elimination method is incorporated into a PC programme with some user-friendly features in problem definition and visualisation of results. An example of a perforated strip in tension is used to estimate the applicability and efficiency of the method. Since in the iteration for simplicity initial stiffness method is used rather than the more efficient tangent stiffness, a relatively coarse convergence criterion had to be accepted. The proposed method seems applicable and promising for some computations such as optimisation of reinforcements in stress concentration zones in clothes (button holes) and other similar situations where flexible materials are loaded in the plane stress conditions.
