Non-Homogeneous Bars under Tension, Pure Bending and Temperature Loads

摘要: Non-homogeneous bars may show discrepancies in stiffness and thermal expansion between the engineering theory of bending experiment. The reason for this are additional stresses perpendicular to bar axis due different Poisson’s ratios used materials. Especially, if fiber reinforced materials used, these have be taken into account. A evaluating those non-homogeneous is shown. Other methods calculation, based on classical laminate also given. Test results good correlation with theory.
