Stress Analysis
Introduction
In engineering field stress analysis is one of the important part, as it deals with the failure of most
engineering components. It determine the stress in metal or structural component which are subjected
to static or dynamic load. Analysis may be performed through experimental testing techniques, through
analytic mathematical modelling or computational simulation or a combination of methods. To
optimize the material properties after undergoing stress analysis different types of experimental test is
carried out. Firstly, the non-destructive testing (NDT) is the process of evaluating the material
components, making differences in characteristics to provide the long serviceability. Other testing
method like ultrasonic testing and magnetic particle testing which are utilized to determine the
physical properties of metal component like impact resistance, ductility, toughness, yield and ultimate
tensile strength. Several mechanical component such as sheet metal, welding joint, engine parts of
vehicle undergo for stress analysis using experimental or FE simulation in order fix the suitable
properties and compositions. Shinde and Thombare (2014) have performed a FE simulation for static
analysis for car bodies. Ren et al. (2017) established a theoretical model and FE model for elastic
deformation to evaluate the residual stress which causes the large deformation of metallic bodies. Wei
and Wang (2007) have developed an effective testing and controlling technique for stress analysis.
Aim
1. To study the different type of stress analysis technique including experimental and FE analysis
