Fatigue Failure Analysis of Rim

thikf9m1kxA new article published in the « International Research Journal of Engineering and Technology« , Aug-2016.

A Finite Element Method methodology is proposed for fatigue life and failure prediction of automotive steel wheel by the simulations of dynamic radial fatigue test (RFT). A short review of theoretical models, numerical simulation models were described in conjunction with bilinear elasto-plastic finite element stress analysis under wheel rotating loading.

Analysis of plastic conveyor Slat belt

automotive failuresA interesting paper in « International Journal of Advance Engineering and Research Development » (IJAERD) published on ijaerd.co.in.

Abstract- McCain Foods, an MNC, manufacturer and supplier of FMCG products located in Gujarat, India was experiencing frequent breakdown in operations. During inspection, the plastic conveyor belt  and gear mechanism were suspected. Stress analysis of a standard plastic modular link of different  height is done using finite element methods. The mechanical behavior of a standard Slat chain which is loaded by the maximum allowed load are considered. The Finite Element analysis has been proved appropriate tool as compared to theoretical computations

Assessment of a gouge and dent defect in a pipeline

This paper pubished in Engineering Failure Analysis, deals with A37 steel pipelines containing a gouge and dent defect. The influence of the dent depth on the burst pressure of pipelines is evaluated for a given geometry of the gouge. Experimental burst tests are performed and finite element analysis is used in order to compare the numerical and experimental results. Experimental results showed that a combined gouge and dent defect does not reduce the burst pressure of A37 steel pipelines. These results contradict established research conclusions and the bulk of the literature on the subject. A combined criterion based on volumetric method and stress triaxiality is proposed for assessment of pipelines containing a gouge and dent defect.
