The fabric composite material is considered. For its representative cell the 3-D finite-element model is developed. The technique of the task decision about its two axes a lengthening and task to construct a limiting surface is given. The results are shown as the diagrams.
пластичность, упрочнение, большие перемещения, предельное равновесие, plasticity, hardening, large displacements, limiting balance
