Numerical Characteristic Length Model for Mechanical Composite Joints in Mechanical Manufacturing Engineering

Abstract:

According to the progressive damage analysis based numerical characteristic length scheme presented by Zhang, a progressive damage model established by Liu is adopted here to calculate characteristic lengths for mechanical composite joints. Four groups of specimens with different lay-ups and geometries were designed and fabricated and static tensile experiments were carried out to verify the suitability of the numerical characteristic length model. Good agreements between the predicted ultimate failure loads of the specimens and experimental outcomes are obtained. In addition, the characteristic lengths calculated from the experimental ultimate failure loads are in accordance with that obtained from numerical ultimate failure loads, which give evidence of the feasibility and suitability of the numerical characteristic length model.
