Effect of cyclic compression
WebMay 27, 2024 · Experimental results show that the interval effect decreases with the increase of the confining pressure. The change in plasticity caused by time intervals is small and constant when the stress level (ratio of the maximum stress to strength) is below “60%” but then increases as a linear function of the stress level. WebCyclic loading in general produced less marked changes than static loading, but loading at particular frequencies may result in more severe changes. Relevance: In this study, a …
