Experimental Finite Element Approach for Stress Analysis

Abstract

This study aims to determining the strain gauge location points in the problems of stress concentration, and it includes both experimental and numerical results. Strain gauges were proposed to be positioned to corresponding locations on beam and blocks to related node of elements of finite element models. Linear and nonlinear cases were studied. Cantilever beam problem was selected as the linear case to approve the approach and conforming contact problem was selected as the nonlinear case. An identical mesh structure was prepared for the finite element and the experimental models. The finite element analysis was carried out with ANSYS. It was shown that the results of the experimental and the numerical studies were in good agreement.

Measurement of Stresses and Strains by Strain Gauge using IoT Platform

“…Limited component investigation for the cross-section of direct and nonlinear circumstances by putting strain checks at the hubs characterizing components in FEM for example Limited component model, set strain measures as indicated by the hub characterizing the components in Limited component model and presumed that separation of strain checks brought about the mistake of up to 10%. Setup was developed for validation of bending stress and flexural formula by comparing Experimental results with theoretical and analytical results conveyed by Ahmet Erklig et al [10].…”

Conceptual Design and Finite Element Fatigue Life Analysis of a Poppet Valve Spring Compressor

“…e results show that the upper frame of the valve spring compressor experienced the highest von Mises stress of 59.77 MPa, which occurred at the neck region, as shown in Figure 10. Hence, attention was given to the upper frame, as it contained a critical stress concentration location [8]. Furthermore, the need to determine the fatigue life of the upper frame became necessary, so as to determine the extent to which the device can be used without the occurrence of fatigue failure.…”
