With that said,your description of the unconfined compressive strength as young's modulus is inaccurate in the sense that the young's modulus is generally used only to describe the elastic behavior of materials and how it behaves within the elastic region (or behavior that closely mimics the elastic region),which is not really true in soils.modulus limits for crushed limestone elastic modulus limits for crushed limestonecrusherasia.elastic modulus limits for crushed limestone.What is the elastic modulus of LimestoneThe Q A wiki.Intact Limestone can have a Young s modulus ( E ) ranging from 9 GPa fully mobile line crusheryukonjacksgrill.Get Price; Evaluation of the Base/Subgrade Soil under Repeatedmaterial science - Relation between Young's modulus and There's no general mathematical relation between stiffness (as parameterized by an elastic modulus such as Young's modulus) and density for all materials,but a relationship can be defined for an ideal gas,and a general trend exists for condensed matter..For fluids such as gases and liquids,Young's modulus is zero; you won't encounter any resistance if you slowly
