Experimental and Analytical Study of Bending Stresses and Deflections in Curved Beam Made of Laminated Composite Material

Abstract Theoretical and experimental methodologies were assessed to test curved beam made of layered composite material. The maximum stress and maximum deflection were computed for each layer and the effect of radius of curvature and curve shape on them. Because of the increase of the us...
