Analysis and statistical interpretation of biaxial material constants derived according to EN 17117-1:2018

Utilising fabrics as an engineering material allows for the creation of lightweight structures, but poses some challenges when it comes to deriving properties use in numerical models due complex composite-like nature these coated fabrics. Until recently, no international standard regarding testing materials and their existed. With publication EN 17117-1:2018, guidelines biaxially test derive constants are now available. To evaluate methodology presented 17117-1:2018 analysis results was carried out. A statistical interpretation allowed evaluation data variability while verifying feasibility a stochastic approach describing derived constants. This latter could be valuable addition e.g. reliability analyses. Results obtained from ten tests utilising suggested discussed evaluated. Next, method verify is proposed. The stress–strain indicate good consistency between conducted tests. process applying distributions showed relatively straightforward yields compatible data. However, limitations, mostly related sample size, still exist.
