The off-axis behavior of a unidirectional fiber-reinforced plastic composite
Tomáš Kroupa, Vladislav Laš
Izvirni znanstveni članek
Oznake: composite;PFA;tensile;non-linear;carbon-epoxy;failure;
Numerical and experimental investigations of the off-axis behavior of a unidirectional fiber-reinforced plastic composite consisting of carbon fibers and an epoxy matrix are presented. Static tensile tests of thin carbon-epoxy composite strips with various fiber directions were performed and simulat ...

Numerical simulation of the progressive damage to FRC panels due to shock loading
Robert Zemčík, Vladislav Laš
Izvirni znanstveni članek
Oznake: FEA;FRC;damage;shock;PFA;
This work focuses on the numerical simulation of failure of composite structures. In the previous study we have developed a computational model for the prediction of the critical state of a structure made of fiber-reinforced composite (FRC) panels and capable of quasi-static simulation of the subseq ...

Numerical determination of J-R curve using void model
Vladislav Laš, Jan Očenášek, Vlastimil Vacek
Izvirni znanstveni članek
Oznake: aluminium;J-R curve;numerical simulation;Complete Gurson Model;CT specimen;
The paper presents the determination of the J-R curve for an aluminium alloy. J-integral value is determined by numerical simulation of the test prescribed in ASTM E 1820-01. The crack growth [Delta]a corresponding to the load increment is determined numerically. The Complete Gurson Model (CGM) base ...
