The invention discloses a complex stress path single shear instrument considering a temperature influence. The single shear instrument comprises a thermal insulation box, an upper cover and a shearingdevice in the thermal insulation box. The shearing device comprises an upper plate and a lower plate. The upper plate is provided with a drainage port. A row of steel balls are arranged between the lower plate and the bottom surface of the thermal insulation box. Several steel rings are arranged between the upper plate and the lower plate. Four holding ears are equally arranged outside the steelrings along a circumference. The holding ears are detachably provided with a connection rod passing through the thermal insulation box and the other end of the connection rod is connected to a cylinder. The single shear instrument considers the temperature influence, accuracy is high and a complex stress path can be simulated.
Description
technical field [0001] The invention relates to a simple shear instrument, in particular to a complex stress path simple shear instrument considering the influence of temperature. Background technique [0002] At present, the simple shear instrument provided on the market generally includes an upper plate and a lower plate, and several steel rings are arranged between the upper plate and the lower plate. This simple shear instrument has a single function, cannot simulate the temperature of a specific environment, and has poor accuracy. Contents of the invention [0003] In view of the deficiency of the background technology, the technical problem to be solved by the present invention is to provide a simple shear instrument which can consider the influence of temperature, has higher accuracy and can simulate complex stress paths. [0004] For this reason, the present invention is to adopt following technical scheme to realize: [0005] A complex stress path single shear in...
