Biaxial Cruciform Testing of Fiber Composite Materials

Popis výsledku v původním jazyce

The biaxial cruciform testing method was adopted to validate the failure criteria results obtained through numerical simulations. A biaxial testing machine was developed, and carbon fiber epoxy laminate specimens were tested. Failure strains were evaluated in the central area of the specimens. Specimens without tabs failed in the arm section, while specimens with glass-fiber tabs failed in the central section. However, both failed prematurely, as confirmed by numerical simulations with a progressive damage model. The first ply failures for the matrix and fibers were evaluated using simulations. The values of the first ply failure strain in the simulation were much lower than the measured ultimate failure strains. This demonstrates that the use of biaxial tests can be advantageous for determining the ultimate failure of components in combination with simulations, even in cases where the specimens fail prematurely.
