The present study concerns experimental and fin ite element analysis of carbon epoxy and carbon epoxy carbon nanotube composites to estimate interlaminar shear strength. Mechanical properties such as elastic ratios, thickness are varied for double notched specimen and the corresponding deflections and interlaminar shear strengths are estimated by ANSYS. From simple ru le of mixtures, equivalent...

Magnetic levitation is a popular topic of research over the years throughout the world due to its wide range of industrial applications. In any DC attraction type suspension system, actuator and guide-way (rail) plays most important role. In this manuscript FEM based analysis of different structures of actuator and rail (guide-way) has been carried out utilizing ANSYS software. Input power to l...

The purpose of this study is to develop a numerical approach to simulate the creep cracking of a Ni-base superalloy. The approach is based in continuum damage mechanics (CDM) and uses the classic Kachanov-Rabotnov constitutive equations for creep deformation and damage evolution. Creep damage takes the form of defects such as microcracks, cavities, voids, etc. A numerical crack growth algorithm...

Carbon fibers were pretreated by ultrasonic agitation and then were used to manufacture carbon fiber-reinforced wood composites (CFRWCs). The modulus of rupture (MOR) and the modulus of elasticity (MOE) for the CFRWCs were measured. The effects of the compounding pattern and proportion of carbon fiber on the dynamic performance were investigated by dynamic thermomechanical analysis (DMA) and fi...
