Novel laboratory equipment has been modified to allow both torsional and flexural oscillation measurements at sub-microstrain amplitudes, thereby providing seismic-frequency constraints on both the shear and compressional wave properties of cylindrical rock specimens within the linear regime. The new flexural mode capability has been tested on experimental assemblies containing fused silica con...

The plate of a pultruded fiber-reinforced polymer or fiber-reinforced plastic (FRP) profile produced via a pultrusion process is likely to undergo local buckling and cracking along the fiber direction under an external load. In this study, we constructed a pultruded glass-fiber-reinforced polymer-light wood composite (PGWC) profile to explore its mechanical performance. A rectangular cross-sect...

This study investigates dynamic & static behaviour of automotive engine crankshaft with the specific conditions. This work investigates the coupled modes, including, couple torsional flexural vibration and coupled longitudinal flexural vibration for non rotating engine crankshaft. The finite element models of this generally used are in two categories beam elements and solid elements and in this...

Automotive drive Shaft is a very important components of vehicle. The present paper focuses on the design of such an automotive drive shat by composite materials. Now a days two pieces steel shaft are used as drive shaft. However, the main advantages of the present design is; only one piece of composite drive shat is possible that fulfil all the requirements of drive shaft. Two different design...
