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

A novel mesoscopic progressive damage model for 3D angle-interlock woven composites
TL;DR: In this paper, a mesoscopic progressive damage model is proposed to investigate the effective properties and damage mechanisms of 3D angle-interlock woven composites, where the damage activation is based on the three-dimensional version of Puck criterion.

TL;DR: In this paper, the solution of two-dimensional non-steady motion problems in two dimensions is studied. But the solution is not a solution to the problem in three dimensions.

The Brittle Strength of Orthotropic Materials
TL;DR: In this article, a phenomenological fracture condition for ortho tropic brittle materials is proposed, which can account for widely differing compressive and tensile strengths in ortho tropical brittle materials.
Invariant properties of composite materials.

TL;DR: The use of these invariants in materials evaluation and design optimization is discussed in this article, where simple formulas, based upon micromechanics results, are derived for the invariant in terms of constituent material properties.

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.

Classic theories of failure of anisotropic materials
TL;DR: In this paper, a modification of Marin's criterion that includes six constants, five of which are evaluated from four uniaxial loading conditions and a pure shear condition, is introduced.
