• ### the difference between static and dynamic analysis | enterfea Oct 25, 2019 · This is where static equivalent of dynamic load comes in play. The idea is simple: just increade the load with the “dynamic factor”! Then you can treat it as static load in your analysis. I saw various “dynamic factors” in my career, starting from a humble 1.5 and going up to around 10 Aug 01, 2017 · Underground rock failure can be induced by dynamic load such as blasting (Ma et al., 2000, Li et al., 2011b, Kaiser and Cai, 2012).
