Frequently asked questions

Q1. What have the authors contributed in "Three-dimensional failure criteria for fiber-reinforced laminates" ?

This paper proposes a new fully three-dimensional failure criteria for polymer composites reinforced by unidirectional fibers. 

Q2. What have the authors stated for future works in "Three-dimensional failure criteria for fiber-reinforced laminates" ?

For higher values of hydrostatic pressure the quality of the predictions is degraded, which means that the future developments of the model should include the simulation of the effect of the hydrostatic pressure on the elastic properties of the composite material. While the proposed failure criteria can be used to predict failure envelopes for all conceivable stress states, it is clear that additional experimental work is required to validate the predictions obtained for multi-axial stress states that include out-of-plane components of the stress tensor. Some of the complex stress states analyzed in this paper are clearly not easy to impose experimentally ; as an alternative, the suggested additional validation of the proposed criteria for complex stress corresponds to the use of non-linear micro-mechanical finite element models where the complex stress/strain states can be applied using appropriate periodic boundary conditions.
