English abstract:
Bi-axial ±45◦ and ±30◦ carbon fiber reinforced polymer braidings are investigated with respect to their mechanical behavior including various modes of damage and plasticity. Nonlinear Finite Element predictions are carried out for a number of load cased up to laminate failure while monitoring the evolution of the material nonlinearities including the softening branch.
The textile structure is represented by a plane periodic unit cell based on shell elements employing constitutive laws for the unreinforced polymer matrix material and the composite yarns. For
the latter, an in-house developed constitutive model is used which includes plasticity and distributed damage.
Predictions are compared to experimental results for the same material system, which are carried out by cooperation partners.
