Abstract: The classical formula for the pressure in deep bins containing granular material is derived here employing considerably weaker assumptions than previous derivations. Three important points are ...

Abstract: Shape intrinsic orthotropy may be thought of as the type of elastic material symmetry possessed by the wood tissue of a tree. Each year’s new growth rings form a laminate around a central ...

Abstract: An elastic constitutive relation for cancellous bone tissue is developed. This relationship involves the stress tensor T , the strain tensor E and the fabric tensor H for cancellous bone. The ...

Abstract: This paper concerns the applications of a method of modeling the mechanism of shrinkage in porous elastic materials. Examples of the effects of shrinkage in porous elastic materials include the ...

Abstract: The pressure ratio K0 is assumed to be a constant in the theory developed by Janssen for determining the pressures imparted by a granular material to its container. Recently it was shown ...

Abstract: A stress analysis of a pencil writing tip at fracture is presented. It is an interesting illustration of combined axial and bending loading.

Abstract: Formulas for the tensile, compressive, and shear strengths along an axis off the grain axis of a material with orthotropic symmetry are derived from the quadratic form of the Tsai-Wu strength ...

Abstract: In this paper we consider an initially inhomogeneous adaptive elastic body subjected to a steady homogeneous stress state. The adaptive elastic body, which is a model for living bone tissue, ...

Abstract: In this paper it is argued and partially demonstrated that the features of Pauwels’ qualitative theory of functional adaptation of bone tissue are expressed mathematically by the cubic approximation ...

Abstract: Lower bounds are derived for the force needed to extract a cylinder from a larger cylinder when the annular region between the two cylinders contains a granular material.
