Notched bar tests - specification for verification of the test machine used for precision determination of charpy v - notch impact energies for metals

In order to verify these criterions , tensile experiments are carried out for many kinds of samples made out of plexiglas with a planar v - notch under mixed - mode of i and ii
Based on the basic equations of the elasticity plane problem , displacement fields and singular stress fields near the v - notch tip under mixed - mode of i and ii are obtained for homogeneous materials by a new definition of the stress intensity factors
The ratios of charpy impact value of small size specimen to that of the standard are studied by using the series charpy v - notch impact test method and the question how to select equivalent ratio of the charpy impact quota of non standard sample is also discussed
Based on the basic equations of the elasticity plane problem and the two airy stress functions in the thesis , stress singularity eigenequations and displacement fields as well as singular stress fields near the v - notch tip and the crack tip for homogeneous materials are obtained
Based on the theory of fracture mechanics , the relation between the critical stress intensity factors for v - notch kc and the plane strain crack toughness k10c and the brittle fracture criterion of the maximum circumferential stress for single and double stress singularity with the v - notch problems are proposed . experiments were carried out using two kinds of v - notched specimens made out of plexiglas to verify this brittle fracture criterion
