A micromechanical model for interpenetrating multiphase composites

The dependence relation between the macroscopic effective property and the microstructure of interpenetrating multiphase composites is investigated in this paper. The effective elastic moduli of such composites cannot be calculated from conventional micromechanics methods based on Eshelby s tensor because an interpenetrating phase cannot be extracted as dispersed inclusions. Employing the conce...

A Mechanical Model and its Experimental Verification for a Water Injection String in a Highly Deviated Well

Water injection strings in highly deviated wells are subjected to complex forces on the string bore. In this work, a mechanical model is developed for these forces and for those on downhole tools. On the basis of this model, and taking account of the characteristics of the string in different working conditions, a temperature field model and a pressure field model are introduced, and a statical...

A model for specification, composition and verification of access control policies and its application to web services

Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...

A Damage Mechanics Model for Compression Strength of Composites

A compression strength model based on damage mechanics and a Gaussian distribution of fiber misalignment is presented. The model uses only three material parameters that can be measured by well established methodologies. The compression strength and all the parameters that enter in the model were measured for the same materials. Predicted values are compared to experimental data for eleven diff...
