Morphogenesis, the process by which all complex biological structures are formed, is driven by an intricate interplay between genes, growth, as well as intra- and intercellular forces. While the expression of different genes changes the mechanical properties and shapes of cells, growth exerts forces in response to which tissues, organs and more complex structures are shaped. This is exemplified...

As a result of the complex configuration of a dental restoration, an analysis of internal stresses utilizing the theory of elasticity is extremely difficult to accomplish. The method of photoelasticity, however, appears to be particularly suitable for such occasions. Many investigators have used two-dimensional photoelastic dental models to study, among others, the effects of rounding axiopulpa...

Abstract Elderly people suffer from more and teeth problems. The tooth-implant-supported prosthesis provides a reliable solution to missing patients. proper dental design prevent overstress is essential due the mechanical characteristics of bridge abutments are different. finite element method widely applied, but experimental validation required. curing shrinkage epoxy applied for photoelastici...

Abstract The transition of polymer adhesives from an initially liquid to a fully cured viscoelastic state is accompanied by three phenomenological effects, namely increase in stiffness and viscosity conjunction with decrease volume (curing shrinkage). Under consideration these phenomena, some us (Hossain et al. Computational Mechanics 46:363-375, 2010) have devised generic, finite strain framew...
