Engineering Constants for a Monoclinic Elastic Solid 313
The symmetry of the compliance matrix requires that
If only TH is nonzero, then the strain-stress law gives
and if only TII is nonzero, then
etc. Thus, EI , £2 and £3 are Young's modulus in thejtj ,Jt2 and ^3 direction respectively and
again, v^ is Poisson's ratio for transverse strain in the /-direction when stressed in the
/-direction. We note also, for the monoclinic elastic solid with ej plane as its plane of symmetry,
a uniaxial stress in the x\ direction, or x^ direction, produces a shear strain in the xi x$ plane
also, with rjij as the coupling coefficients.
If only 7j2 = 7*2] are nonzero, then,
and if only 7\3 = T^j are nonzero, then,
