Photographic Analysis

The mechanical property of polyvinyl chloride (PVC) geomembrane was usually expressed using engineering stress-strain response in traditional uniaxial tension test. By failing to account for deformation of specimen during the test, the deviation of true stress and strain maybe caused from the test results. In this paper, the true stress-strain response of PVC geomembrane was investigated using uniaxial tension test. The photographic analysis method was used to measure axial and lateral true strain of specimen. The Poissons ratio and true stress were also acquired based on measured true strain in the test. Then the true stress-strain relationship was obtained from the test results. By comparing with the engineering stress-strain results expressed by traditional method, it can be found that the engineering stress-strain result is unreasonable. The engineering stress-strain expression easily leads to the underestimation of the true stress.

In this paper, the rule of mixture, which is often used to derive the weld properties from the uniaxial tension test of a subsize welded specimen, was improved by taking the residual welding strain/stress into account and assuming iso-strain increment across the welded specimen. Based on this improved method, hardening data of two different tailor welded blanks were determined. Erichsen cupping tests were performed experimentally and numerically to evaluate the effects of welding residual strain and stress on TWB formability. The results indicate that: (1) the residual strain and stress affect the formality of TWBs to some extent and (2) neglecting the welding residual strain and stress may predict a delayed crack onset and relatively large values in the maximum punch load and Erichsen index.
