A new constitutive model for drying of an elastic porous material is presented. The model is derived by decomposing the boundary value problem of drying into parts for which an explicit solution is readily available. The mathematical form differs frommodels developed using either the concept of equivalent pore pressure or average pore pressure. Instead of pressure averaging, the extent of weake...

In this study buckling analysis of solid rectangular plate made of porous material bounded with the layers of piezoelectric actuators in undrained condition is investigated. Porous material properties vary through the thickness of plate with a specific function. Distributing of the pores through the plate thickness is assumed to be the nonlinear nonsymmetric distribution. The ...

This article reports a new process chain for custom-made three-dimensional (3D) porous ceramic scaffolds for bone replacement with fully interconnected channel network for the repair of osseous defects from trauma or disease. Rapid prototyping and especially 3D printing is well suited to generate complex-shaped porous ceramic matrices directly from powder materials. Anatomical information obtai...

Abstract Analytical expressions are derived for the longitudinal flow in a superhydrophobic microchannel where flat menisci Cassie state have partially invaded grooves between no-slip blades. Using these solutions, effective slip lengths computed and compared with recent analytical results unbounded shear over same class of surfaces. Expressions first-order corrections to when weakly curved als...

Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...

OBJECTIVES The purpose of the present study was to evaluate bone healing in rabbit critical-sized calvarial defects using two different synthetic scaffold materials, solid biodegradable bioactive glass and tricalcium phosphate granules alongside solid and particulated autogenous bone grafts. MATERIAL AND METHODS Bilateral full thickness critical-sized calvarial defects were created in 15 New ...
