Sažetak
In this paper we present a part of the initial efforts at our Faculty of textile technology to introduce numerical modelling and computational mechanics to the field of textile and clothing engineering. Ignoring for the time being some other mechanical features of textile as a complex structure, such as anisotropy, non-homogeneity, non-linearity in extension and hysteretic behaviour in cyclic loading, we focus our attention to the description of non-linearity related to the flexibility, or in other words to the lack of compressive carrying capacity. In doing so, we explore some computational experience gained elsewhere in the context of metal plasticity &#8211 ; ; in fact in the iterative numerical procedure, section 2, the step of stress reduction to the compressive limit is very similar to the return mapping algorithm in computational plasticity. Finally, an emphasis is given to the examples, section 3. On one side, they illustrate some possibilities of our home-developed computer programme, and on the other they show an analysis of a selected problem relevant for the practical case of stress concentration in clothing.
