    Simple Stresses

    SIMPLE STRESSES  Stress: It is the internal resistance of a material against the external force applied. Mathematically stress = force/area =N/mm2. Simple stress is due to only one type of load applied. Simple tensile stress when only tensile load is applied. Tensile load is perpendicular to the area and coming out of the area (like […]

    Stresses and Strains in a Composit Beam

    BENDING STRESSES & STRAINS IN COMPOSITE BEAMS DEFINITION OF A COMPOSITE BEAM A beam of two or more materials is a composite beam. STRESSES AND STRAINS IN COMPOSITE BEAMS Derivation of bending equation assumes the material is homogeneous and isotropic. A composite beam cannot satisfy this assumption. Therefore, a composite beam is converted into a […]
