A rectangular plate of composite material is formed with unidirectional fibres orientated at 30 degrees to the longitudinal axis. The composite material has properties in the principal material directions of E₁ = 150 GN/m², E2 = 45 GN/m², V12 = 0.28, V21 = 0.37 and G₁2 = 75 GN/m². A stress of 60 MN/m² is applied to the plate on the longitudinal direction? What is the strain in this direction. Give you answer in micro-strain.
