QB3 TWO DIMENTIONAL STRAIN
Three strain gauges were arranged in the form of a rectangular rosette and positioned on a
test surface. The measured strains were as follows:
1 = 200x 10-6
2 = 100 x 10-6
3 = 50 x 10-6
Determine
a) the principal strains and the principle stresses
b) the direction of the greater principal strain relative to gauge 1 and sketch the Mohr
strain circle. Take the Young Modulus of Elasticity value to be E = 200 GN/m2 and
Poisson’s ratio = 0.28.
