This paper presents an attempt at the numerical modelling of a model that has been developed for a glass-fiber reinforced epoxy laminate (10-layer) square plate, supported on a circular support and loaded centrally with a spherical indenter. The determination of the stress corresponding to the initiation of the material failure process under such loading conditions has also been presented. ALGOR software was used for the numerical modelling. It was found that the performed analysis can be efficiently used to evaluate the properties of a material subjected to a compound stress state. This has been proven effective to determine the stress level in the material. The analysis of the determined characteristics based on the evaluation of the load value oscillation amplitude in the final portion of the curve may be proposed for detecting the moment of failure initiation in materials during mechanical tests.

Artykuł jest kontynuacją pracy pt. Behaviour of plain-woven glass-fiber reinforced polymer laminate plates during symmetrical bending on a circular support – Part I: Experimental evaluation [14]. Jego celem jest wyznaczenie naprężenia w próbce laminatu podpartej na podporze kołowej i obciążanej centralnie za pomocą modelowania numerycznego i z wykorzystaniem danych eksperymentalnych uzyskanych we wspomnianej pierwszej części pracy. Po ustaleniu skutecznej procedury obliczania naprężenia będzie możliwe wyznaczenie naprężenia odpowiadającego początkowi procesu zniszczenia w materiale oraz ocena zachowania się laminatu w założonych, bardzo skomplikowanych, warunkach obciążania.
