Question
A body is subjected to uniaxial tensile
stress of 20 MPa in the y-direction as
well as a temperature decrease of 10
degrees K. The material's elastic
modulus is 90 GPa, the Poisson's ratio
is 0.20, and the coefficient of thermal
expansion is 12E-6 per degree K.
What are the normal strains in the x, y,
and z directions (microstrain units) ?
