Question

The Mohr’s theory of failure can be symbolically expressed as ____________

(a) τmax=F(σn) and σmax–σmin = f(σmax +σmin)

(b) τmax = σmax– σmin

(c) None of the mentioned

(d) All of the mentioned

This question was posed to me in semester exam.

I'd like to ask this question from The Mohr topic in chapter Failure Envelopes & Earth Pressure of Geotechnical Engineering II

Answer 1

Right option is (a) τmax=F(σn) and σmax–σmin = f(σmax +σmin)

To explain I would say: Mohr’s theory of failure can be symbolically expressed as:

σmax–σmin = f (σmax +σmin) or τmax=f (σn).
