Loading rate effect on the uniaxial compressive strength

WebJun 9, 2015 · These cycles were repeated by increasing the peak stress in 15% stress increments of the UCS until failure. All cyclic tests were conducted at room temperature on dry, as-collected specimens at a strain rate of 10 −5 s −1. High Temperature Experiments WebJul 17, 2024 · The results show that the peak strength and peak strain of marble increase with the increase of loading rate at different temperatures. When the temperature rises to 800°C, the peak strength of marble becomes less obvious with the change of loading rate The modulus decreases with the increase of temperature. ć��t8m
