Thick-Walled Materials Weldability Assessment Based on Test SEP 1390

Hodograph Method of Nonlinear Stress Analysis of Thick - Walled Cylinders and Spheres , including Porous Materials

AbstraetA new method is developed, analogous to a hodograph method, for the nonlinear finite strain and stress analysis of thick-waged cylinders and spheres under internal and external pressure. The problem is reduced to solving a single ordinary differential equation of the first order. It is applicable to plastic or elastic materials. The case of porous cylinder with fluid seepage is also dis...

Dev121723 1390..1395

Lysophosphatidic acid (LPA) is a bioactive phospholipid that is present in all tissues examined to date. LPA signals extracellularly via cognate G protein-coupled receptors to mediate cellular processes such as survival, proliferation, differentiation, migration, adhesion and morphology. These LPA-influenced processes impact many aspects of organismaldevelopment. Inparticular, LPAsignallinghasb...

Creep Stress Redistribution Analysis of Thick-Walled FGM Spheres

Time-dependent creep stress redistribution analysis of thick-walled FGM spheres subjected to an internal pressure and a uniform temperature field is investigated. The material creep and mechanical properties through the radial graded direction are assumed to obey the simple power-law variation throughout the thickness. Total strains are assumed to be the sum of elastic, thermal and creep strain...

Hemocompatibility assessment and drug release kinetics investigation from materials based on electrospun nanofibers

Objective(s): Polymeric nanofiber has a huge potential for a various biomedical applications such as wound healing and orthopedic implant. Since most of the future applications of therapeutic nanofiber are interacting with human blood components, it is important to investigate hemocompatibility. Methods: In this study, nanofibers with antibacterial properties were synthesizedby elec...
