The effect of a linear applied shear stress gradient on the yield stress of a dislocation pileup is investigated analyti- cally using the continuum theory of dislocation pileups. The solution agrees well with numerical discrete dislocation simulation

The intrinsic lattice resistance to dislocation motion, or Peierls stress, depends on the core structure of the dislocation and is one essential feature controlling plastic anisotropy in materials such as HCP Zn, Mg, and Ti. Here, we implement an ani

This study determined which knee joint motions lead to anterior cruciate ligament (ACL) rupture with the knee at 25° of flexion. The knee was subjected to internal and external rotations, as well as varus and valgus motions. A failure locus represen

A new model, stress-gradient plasticity, is presented that provides unique mechanistic insight into size-dependent phenomena in plasticity. This dislocation-based model predicts strengthening of materials when a gradient in stress acts over dislocati

The combined effect of dislocation source strength tau(s), dislocation obstacle strength tau(obs), and obstacle spacing L(obs) on the yield stress of single crystal metals is investigated analytically and numerically. A continuum theory of dislocatio

We consider the evolution of slender viscous fibres with cross-section containing holes with application to fabrication of microstructured optical fibres. The fibre evolution is driven by either prescribing velocity or a force at the ends of the fibr

The strength of optical fibers with a thin brittle coating is examined. The inert strength of optical fibers coated with carbon (hermetic fibers) has been observed to be less than that of standard optical fibers. A fracture mechanics model was develo

This study uses a three dimensional model of the knee joint to determine which knee joint motion schemes lead to ACL injury, while exploring the possible types of concomitant injuries associated with each motion scheme. The physical elements of the k
