Coronary anastomotic devices: Theory and patented ideas on micromechanical fastening
Current Cardiology Reports, 2000Coronary anastomotic devices are being designed to reduce the laborious, complex suturing approach to endoscopic coronary surgery. An anastomotic device should be safe and reliable, it should allow full view of the vessel parts to be bonded, it must provide a simple and rapid deployment, and should be hemodynamically adequate.

A Micromechanical Theory of High Temperature Creep
Journal of Applied Mechanics, 1987Based on the mechanism of dislocation climb-plus-glide, a micromechanical theory is developed for the high-temperature creep of polycrystals. This model assumes that dislocation climb is responsible for the release of dislocations and whose subsequent glide provides the only significant contribution to the overall creep strain.

A micromechanical sub-modelling technique for implementing Onset Theory
Composite Structures, 2013Abstract A multi-scale modelling approach is described for implementation of the micromechanics-based Onset Theory for laminated composites. Micromechanical sub-models derived from a laminate shell or layered solid finite element model enable direct de-homogenised strain fields to be investigated without the need of strain enhancement factors.

On the micromechanics theory of Reissner-Mindlin plates
Acta Mechanica, 2000A micromechanics model is developed for Reissner-Mindlin plates based on a generalized eigenstrain formulation. In this framework, the author obtains an analytical solution for elliptical inclusion embedded in an infinite thick plate. In particular, the first-order asymptotic solution of the elliptical inclusion problem is obtained in explicit form. As

A micromechanically consistent poroviscoelasticity theory for rock mechanics applications
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1993Rocks can exhibit viscoelastic properties, depending on the loading conditions, the environment, and the time scale of interest. For fluid saturated rocks, the coupling effects between pore pressure diffusion and rock matrix deformation give rise to similar but different time dependent phenomena.

A micromechanical theory of fatique crack initiation from notches
Mechanics of Materials, 1982Abstract The fatigue crack initiation along the slip banks emanating from notches is analyzed theoretically with the use of the dislocation dipole accumulation model proposed previously by the authors. The complex function analysis for an elliptical notch under the anti-plane shear gives a quantitative method for assessment of the reduction of ...
