Název v původním jazyce

Temperature dependence of parameters of non-linear stress-strain relations for carbon-epoxy composites

Popis výsledku v původním jazyce

This work focuses on the identification of parameters of stress-strain relations of unidirectional continuous fiber carbon-epoxy composite under tensile loading for various temperatures. Simple tensile tests of thin strips with various fiber orientationsare performed. Identification of parameters for chosen non-linear stress-strain relations is performed for each temperature for which the experiment is performed. Consequently, the identification of strengths is performed. The failure analysis for the determination of the first failure with the use of Puck's action plane concept is performed, whereas the tensile and shear strengths are investigated. The identification process with the use of the combination of the mathematical optimization method and finite element analysis is described with the necessary details. The temperature dependence of parameters is also investigated.
