With the goal of examining the micromechanics damage characteristics of freeze-thaw red sandstone under the influence of cyclic loads. a model of freeze-thaw cyclic rock particles is developed based on Discrete Element Method numerical simulation in order to investigate and study the micromechanics response mechanism of rocks under the coupling effect of freeze-thaw and cyclic loads. ... https://halohealthcarers.shop/product-category/transfer-commode-chairs/
