Dynamic Stress Concentration – a Hybrid Analysis

Dynamic Stress Concentrations are being increasing critical in variety of micro-fluidic channels and other devices with sharp corners and edges. The Finite Element Method (FEM) is widely used as a numerical simulation system. Additional Photoelasticity is one of the more widely used experimental methods for verification of the FEM models. This has been done widely for static loading situations. In this paper dynamic Stress Concentration Factors are determined numerically using FEM and experimental using a novel dynamic photoelastic system. It is found that the results from the finite element analysis resemble closely the experimental patterns recorded.
