Abstract

Cilj ovog rada je dati pregled i teoretske osnove fenomenoloških kriterija popuštanja temeljenih na fizici (engl. physically based phenomenological criteria), točnije Puck i LaRC05 kriterija. Puck-ov, Hashin-ov i Tsai-Wu kriterij su implementirani u programski paket MATLAB te je napravljena validacija krivulja popuštanja za materijal IM7/8552. U programskom paketu CATIA je napravljena geometrija karakteristične kompozitne komponente korištene u konstrukciji zrakoplova, te je u programskom paketu Abaqus/Standard® proveden proračun čvrstoće po LaRC05, Hashin i Tsai-Wu kriteriju. Na kraju su uspoređeni rezultati tih kriterija.

Abstract (english)

The aim of this paper is to provide an overview and theoretical foundations of physically based phenomenological criteria, specifically the Puck and LaRC05 criteria. The Puck criterion and the Tsai-Wu criterion are implemented in the MATLAB software package, and visualization of the failure curves for the IM7/8552 material is created. In the CATIA software package, the geometry of a characteristic composite component used in aircraft structures is made, and in the Abaqus/Standard® software package, a strength analysis according to the LaRC05, Hashin, and Tsai-Wu criteria is conducted. Finally, the results of these criteria are compared.
