A Study of Mesh Influence in Numerical Modelling of Stress Concentration in Textile

In this paper the influence of finite element mesh density on accuracy of results is investigated in the example of mechanically weakened zones in clothes, such as vicinity of buttonholes. For this purpose two examples are modelled as corresponding to test specimens for tensile experiments on fabric strip with transverse cut and circular hole. The examples are modelled in a programme developed by authors in Microsoft Visual Basic and in MATLAB software. Four mesh densities are investigated and results in both programs confirm the assumption that with increase of number of finite elements results accuracy is improved.
