Abstract

The fatigue is mostly the common cause of failure in most structural elements subjected to repeated and cyclic loads. This is mostly localized and takes place in elements of constant cyclic load application. This project deals with the fatigue in leaf spring carried out in spring steel 55SiMn90 to find the premature failure in the leaf spring due to variation in application of load. The spring is subjected to both tensile and compressive stress by means of fatigue testing machine. The leaf spring is obtained from the light commercial vehicle and it is subjected to varying stress until the failure occurs in the material. The results are obtained from the test specimen is evaluated to find its tensile and compressive strain. These values obtained will be helpful in analyzing the failure of the material subjected to reversed stress. It is also used for assistance to arrest the failure by implementing measures to culminate the effect of failure to certain extent. B. M. Swami Punniakodi | N.
