Abstract

The invention relates to a composite type fracture test loading device including a pair of C-shaped arc plates which face each other in the vertical direction and are coplanar; each C-shaped arc plate is provided with a circular arc chute for fixing the C-shaped arc plate on a testing machine through positioning bolts; the inner walls of the C-shaped arc plates also are respectively fixedly provided with cross fixing parts facing each other in the vertical direction; the cross-shaped parts are each provided with a cross-shaped groove for clamping a specimen, each cross-shaped groove comprises a first clamping groove and a second clamping groove vertically crossed with each other, and each cross-shaped fixing part surface is divided into four convex stand columns by the cross-shaped groove, each stand column is provided with fixing holes having two axes perpendicular to each other and corresponding to connecting holes on the specimen, and each fixing hole is internally provided with a bolt for connecting the specimen and fixing the specimen in the cross-shaped groove. The I/II type and I/III type composite fracture test loading is achieved, and the test loading device having simple structure and continuously adjustable angle is provided for studies of fracture properties of materials.

Description

technical field [0001] The invention relates to the field of material fracture research, in particular to a composite fracture test loading device. Background technique [0002] Material fracture is a common failure mode. In the field of engineering, catastrophic accidents caused by cracks often occur. These extremely destructive accidents have caused great losses to society. Therefore, the research on fracture mechanics of materials has very important practical significance and application prospects. Obtaining effective data with the help of corresponding test tools is a key link in fracture mechanics research. [0003] At this stage, the devices used in domestic composite fracture tests can only perform tests at several fixed angles, and cannot continuously adjust the angles, or have complex structures, difficult operations, and inconvenient assembly and disassembly, which greatly affect the acquisition of test data and theoretical analysis and research. .
