Abstract
Structural members subjected to external load achieve extra strength by an initial permanent deformation. During the initial stages of elasto-plastic deformation, increasing stress is needed to cause plastic strain in the member, due to strain hardening. In practice, the stresses imposed by service loadings are likely to be complex. When safety factors are reduced to save weight the stresses in the material will approach the yield condition. In most conventional engineering alloys, plasticity will offer the safety margin required. The present study examines the critical elasto-plastic load carrying capacity of AlSiC MMC rod under combined axial and shear stress states. The Aluminium alloy composite materials consist of high specific strength, high specific stiffness, more thermal stability, more corrosion and wear resistance, high fatigue life. Aluminium alloy materials found to the best alternative with its unique capacity of designing the materials to give required properties. In this project torsional strength experiments have been conducted by varying mass fraction of SiC (3%, 7%, 10%, and 20%) with Aluminum. to attain maximum torsional strength. Various mechanical behavior also has to investigated.
