Study of Welded Joint Failure at Negative Temperature
摘要
An experimental-computational study of the strength of welded samples with a crack-like defect under conditions of negative climatic temperatures has been carried out in the current work. A brittle fracture model of a part with a crack has been presented. A finite element analysis of the stress-strain state of the samples has been performed. It has been presented that the test results do not contradict the fracture model. The model evaluates the lower limit of the strength of the part with a crack-like concentrator.
