Polyaxial strength criterion and closed-form solution for squeezing rock conditions
In this paper, a nonlinear strength criterion is proposed using the average of intermediate (σ2) and minor (σ3) principal stresses in place of σ3 in Ramamurthy (1994)'s strength criterion.

Core crush criterion to determine the strength of sandwich composite structures subjected to compression after impact [PDF]
In this study a core crush criterion is proposed to determine the residual strength of impacted sandwich structures. The core of the sandwich is made of a Nomex Honeycomb core and the faces are laminated and remain thin.

Localization-delocalization transition in one-dimensional electron systems with long-range correlated disorder [PDF]
We investigate localization properties of electron eigenstates in one-dimensional (1d) systems with long-range correlated diagonal disorder. Numerical studies on the localization length $\xi$ of eigenstates demonstrate the existence of the localization ...

Empirical Shear Strength Criterion for Artificial Joint
Abstract An accurate understanding of shear strength in joints is critical to effective geotechnical engineering. The complete rock shear test continues to shear after shear strength reaches it speak value, resulting in the appearance of a softening stage and a residual stage.

Anisotropic behaviour law for sheets used in stamping: A comparative study of steel and aluminium [PDF]
For a car manufacturer, reducing the weight of vehicles is an obvious aim. Replacing steel by aluminium moves towards that goal. Unfortunately, aluminium's stamping numerical simulation results are not yet as reliable as those of steel.

Method of strength analysis for doubly-curved stiffened orthotropic shells by various strength theories [PDF]
The paper proposes a method of strength analysis for materials of thin-walled shell structures reinforced with stiffeners. The shells under consideration were made of orthotropic materials.

A new strength criterion for structured soils
AbstractExisting strength criteria are mostly formulated to describe the mechanical properties of reconstituted soils. However, the engineering characteristics of structured soils are different from those of reconstituted soils in many aspects, especially in their strength properties.
