Uncertainty of properties and failure load in composite materials

Abstract
The impreciseness (uncertainty) of the experimentally obtained data can be described using fuzzy sets theory. It is proposed the fuzzy set method for the correct and concise evaluation of various geometrical and mechanical properties or final failure load. The variability (understood as the fuzziness) of the fiber and matrix properties is described by a membership function. Based on experimental results it is possible to determine the effect of the fuzziness of the mechanical properties. The fuzzy sets theory allows to build the lower and upper bounds of the failure envelopes for the Tsai-Wu criterion. The linear qualifier function is applied to analyze the composite structure subjected to the load.
