The curve obtained by plotting the normal and shear stress is called as___________
If the normal and shear stress corresponding to failure are plotted, then a curve is obtained .The plot or the curve is called the strength envelope.
Which of the following is coulomb’s strength equation?
Coulomb defined the function F (σ) as a linear function of σ and gave the following strength equation:
S = c + σ tan φ.
The critical shear stress causing failure of material depends upon____________
According to Mohr’s strength theory, the critical shear stress causing failure depends upon the properties of the materials as well as on normal stress on the failure plane.
Theory of failure, was first proposed by____________
The theory of failures was first expressed by coulomb in 1776 and later generalized by Mohr.
The Mohr-Coulomb theory can be expressed algebraically by, which of the following equation.
The Mohr-Coulomb failure theory can be expressed algebraically by the equation:τf = s = F (σ)
Where, τf = s=shear stress on failure plane, at failure=shear resistance of material
F (σ) = function of normal stress.
