Abstract
Wedge Splitting Tests (WST) is a method to perform stable fracture mechanics tests on quasi-fragile materials which provides a relatively simple manner to obtain the specific fracture energy parameter GFIusing simple specimens like cubes or cylinders [1]. The stability of the fracture propagation depends on the interaction between of the control parameter chosen (displacement or deformation control), the stiffness of the testing machine, the specimen stiffness and the specimen geometry, as well ...
