TL;DR: In this paper, the elastic modulus of hybrid particle/short-fiber/polymer composites was studied using the rule of hybrid mixtures (RoHM) equation and the laminate analogy approach (LAA).

TL;DR: In this paper, the variational boundary integral method of Xu and Ortiz is used to study dislocation nucleation from atomically sharp cracks under combined mode I-mode II loading, and the tension shear potential of Rice et al. is extended to allow for skewness in the shear resistance curve and to account for the surface production resistance which accompanies ledge formation.

TL;DR: In this article, a variational boundary integral method with an interplanar tension-shear potential is used to solve for saddle-point configurations of embryonic dislocation loops and their associated energies.

TL;DR: In this article, a finite element methodology for analyzing propagating cracks of arbitrary three-dimensional geometry is developed, where the opening displacements of the crack as a distribution of dislocation loops and minimizing the corresponding potential energy of the solid, the kernels of the governing integral equations have mild singularities of the type 1/R.

TL;DR: Montmorillonite/epoxy nanocomposites were prepared by incorporating the organo-MMT slurry modified by acidified 2,4,6-tris-(dimethylaminomethyl) phenol (DMP-30) into the mixture of diglycidyl ether of bisphenol-A (DGEBA) and PU modified bisphensol-a using methyltetrahydrophthalic anhydride (MeTHPA) as the curing agent as discussed by the authors.
