TLDR
In this article, an operationally simple strength criterion for anisotropic materials is developed from a scalar function of two strength tensors, which satisfies the invariant requirements of coordinate transforma tion, takes into account the difference in strengths due to positive and negative stresses, and can be specialized to account for different material symmetries, multi-dimensional space, and multi-axial stresses.Abstract:
An operationally simple strength criterion for anisotropic materials is developed from a scalar function of two strength tensors. Differing from existing quadratic approximations of failure surfaces, the present theory satisfies the invariant requirements of coordinate transforma tion, treats interaction terms as independent components, takes into account the difference in strengths due to positive and negative stresses, and can be specialized to account for different material symmetries, multi-dimensional space, and multi-axial stresses. The measured off-axis uniaxial and pure shear data are shown to be in good agreement with the predicted values based on the present theory.read more

Stress analysis in specimens made of multi-layer polymer/composite used for hydrogen storage application: Comparison with experimental results
TL;DR: In this article, a technological specimen representative of hydrogen type IV high pressure storage vessel is studied, and a three-dimensional finite element model is used to compute stress fields and post-processing script is developed to compute three dimensional Tsai-Wu criterion and is entered in the model to determine failure.

Piotr Paczos,Jerzy Zielnica +1 more
TL;DR: In this paper, the authors presented a derivation of the stability equation and the solution method of the problem for an orthotropic elastic-plastic open conical shell, where the shell is free supported at the edges and the load acting the shell, in the form of longitudinal force and lateral pressure, is active one.

Comparison of unit cell-based computational methods for predicting the strength of wood
TL;DR: It is found that together the latter two approaches are able to enclose the experimentally-obtained failure regions for clear wood almost perfectly, while also delivering new insights with respect to the ductile failure potential of wood.

Strength of glass-reinforced plastics in the complex stress state
I. I. Gol'denblat,V. A. Kopnov +1 more
TL;DR: In this paper, a tensor invariant strength criterion for anisotropic materials of the glass-reinforced plastic type is proposed, which takes into account not only the different ultimate strengths in tension and compression in each direction but also the dependence of the ultimate shear strengths on the sign (direction) of the shear stresses.
