The behavior of woven orthotropic composite lamintates in static and fatigue off-axis loading is described. It is shown that all phenomena: linear and nonlinear deformation: accumulation of damage, measured as change of cyclic modulus or hysteresis loop: and the static and cyclic strength can be described by single master curves using generalized stress and strain functions. These functions always contain the quadratic expressions of invariants of orthotropy, but coefficients of invariants depend on the severity of nonlinearity in the described processes or phenomena.
