Problems on young's modulus
WebbYoung's modulus is a measure of the stiffness of an elastic material, and it is defined as the ratio of stress to strain. Rocks with low Young's modulus tend to be ductile and … Webb25 feb. 2015 · Therefore, I add a Domain ODE module and write ‘EE- (10* (fsi.mises>1e5)+2e8* (fsi.mises<=1e5))’ in the source term (EE is the dependent variable, namely young's modulus), and the initial value for EE is 2e8, but the result shows that young’s modulus does not go down to 10 if the stress exceeds the certain value, like …

Webb8 juli 2013 · The Modulus is the remainder of the euclidean division of one number by another. % is called the modulo operation. For instance, 9 divided by 4 equals 2 but it remains 1. Here, 9 / 4 = 2 and 9 % 4 = 1. In … WebbShear modulus equation: The shear modulus of the material can be calculated by use of the following formula. G = Shear stress Shear strain Shear stress Shear strain = τ γ τ γ. Or. G = P L A. x P L A. x. Where, P = Shear force. L = Height of the object perpendicular to the shear force. A = Shear area.
