Extrusion, slide, and rupture of an elastomeric seal

Submitted by Zhengjin WANG on

Elastomeric seals are essential to two great technological advances in oilfields:  horizontal drilling and hydraulic fracturing.  This paper describes a method to study elastomeric seals by using the pressure-extrusion curve (i.e., the relation between the drop of pressure across a seal and the volume of extrusion of the elastomer).  Emphasis is placed on a common mode of failure found in oilfields:  leak caused by a crack across the length of a long seal.  We obtain an analytical solution of large elastic deformation, which is analogous to the Poiseuille flow of vi

New background of micromechanics of composites

Submitted by Valeriy Buryachenko on

Dear Colleagues,

One proposes a new background of micromechanics (NBM) of composites. NBM offers opportunities for a fundamental jump in multi-scale and multi-physics modeling of random heterogeneous media with drastically improved accuracy of local field estimations. In so doing, a difference of linear effective properties estimated by the use of either the new background or the classical one (proposed in 1830-1880) is not significant. See the abstract attached describing a list of 40 papers and conference presentations dedicated to the NBM.

 

A slip wave solution in anti-plane elasticity

Submitted by Ranjith Kunnath on

Abstract:

It is shown that a slip wave solution exists for anti-plane sliding of an elastic layer on an elastic half-space. It is a companion solution to the well-known Love wave solution.
