Effect of a curved fiber on the overall material stiffness

•The effect of fiber curvature on the overall material stiffness is studied.•The stiffness contribution tensor (N-tensor) formalism is used for the analysis.•N-tensors of individual fibers are calculated numerically and estimated analytically.•Proposed approximation procedure gives good predictions...
