“…In the background, a much wider range and more extensive studies are available in the literature; some of them have been included in the World Wide Failure Exercises (WWFE-I~III) [6][7][8], of which references [4,5] were a part. Another popular criterion is the Tsai-Wu criterion, which has been recently rationalized by the author and his co-workers in [9]. It will be employed in the case study, as will be presented in Section 6 of this paper later.…”

The maximum strain failure criterion is unified with the maximum stress failure criterion, after exploring the implications of two considerations responsible for this: (1) the failure strains for the direct strain components employed in the maximum strain criterion are all defined under uniaxial stress states, not uniaxial strain states, and (2) the contributions to the strain in a direction as a result of the Poisson effect do not contribute to the failure of the material in that direction. Incorporating these considerations into the maximum strain criterion, the maximum stress criterion is reproduced. For 3D stress/strain state applications primarily, the unified maximum stress/strain criterion is then subjected to further rationalization in the context of transversely isotropic materials by eliminating the treatments that undermine the objectivity of the failure criterion. The criterion is then applied based on the maximum and minimum direct stresses, the maximum transverse shear stress and the maximum longitudinal shear stress as the invariants of the stress state, instead of the conventional stress components directly.

“…In this study, we have selected the commonly used methodology [40] 12 = −0.5 √ 11 22 which also satisfies the condition 2 12 < 11 22 . Furthermore, for the recent discussions about the calculation of 12 , study of Li et al [41] can be checked. Various models have been proposed by researchers to predict these directional strengths.…”

The outline of this study examines the elastic limit stresses and failure of rotating variable thickness disk composed of fiber reinforced material via utilizing Tsai-Wu criterion. As known, strength parameters ( , ), obtained with the tensile and compressive strength of the material, should be calculated to apply this criterion. In the literature, one may come across different approaches that predicts the tensile and compressive strength of the fiber reinforced composites in different material directions. In the study, these approaches are gathered and the ones estimating lower and upper bound strengths are determined. Followingly, elastic limit angular velocity and position of the failure along the disk is calculated with the criterion for lower and upper bound estimations. It has been seen that usage of lower and upper bound strengths can change the magnitude of elastic limit angular velocity up to 35% without altering the position of the failure. On the other hand, the application of different boundary conditions changes the position of the failure in the disk. When the disk has free-free boundaries, it fails at an arbitrary position. However, subjecting the disk to fixed-free boundary condition cause failure at the inner radius.

“…The reader may be interested in work by Li et al. [30], which gives a thorough discussion on how the interaction term affects yield surfaces in the context of unidirectional composite laminates. The first interaction term of the Tsai–Wu criterion was calculated using the yield strengths in Table 2 as X12=X11−12X66=−0.4145 MPa −2 .…”

The objective of this study was to characterize the multiaxial, elastic-plastic and hysteresis behavior of Divinycell PVC H100 foam using a novel pressure vessel experiment. Cyclic, elastic and post-yield behavior of the foam under uniaxial compression and tension, shear, biaxial compression and shear, triaxial compression, triaxial compression-tension and triaxial compression and shear were obtained in both out-of-plane and in-plane directions of the foam. In all the above-mentioned modes, the foam exhibited elastic-plastic response followed by damage and viscoelastic hysteresis. The Tsai–Wu failure criterion was found to be superior in predicting yielding under triaxial stress states among all the anisotropic yield criteria considered. Based on the experimental results, an elastic-plastic, viscoelastic damage model was developed and used to obtain transversely isotropic, plastic strain hardening behavior as well as viscoelastic and damage properties associated with post-yield hysteresis.
