Dynamic Tensile Properties of Clay Bricks
More severe end crushing can be observed on the low-strength bricks specimen at the high loading rate, 64.73 GPa/s and 60.37 GPa/s for Common Solid and Limestone respectively. This is because of the increased stress wave intensity applied through the incident bar onto the specimen. Download : Download high-res image (2MB)
