Mechanical properties and cracking behaviour of marble and moulded gypsum under high strain rates
Published 2015“…The mechanical properties of both intact and non-intact specimens including the compressive strength, the tensile strength, the elastic modulus, and the failure strain are tested under different strain rates by using a servo compression machine and a split Hopkinson pressure bar (SHPB) system. Experimental results reveal that these mechanical properties all show strain rate-dependence to different degrees. …”
