Modeling of Hygrothermal Damage of Composite Materials
Composite materials have been used extensively in various applications, such as mechanical engineering, aerospace engineering, and aviation thanks to their interesting mechanical properties. However, a substantial drawback in the use of such composite materials is that they absorb a significant amount of moisture when exposed to severe hygrothermal conditions. This factor dramatically affects t...
متن کاملA New Approach to Buckling Analysis of Lattice Composite Structures
Buckling strength of composite latticed cylindrical shells is one of the important parameters for studying the failure of these structures. In this paper, new governing differential equations are derived for latticed cylindrical shells and their critical buckling axial loads. The nested structure under compressive axial buckling load was analyzed. Finite Element Method (FEM) was applied to mode...
متن کاملA Micro–Macro Approach to Modeling Progressive Damage in Composite Structures
Modeling progressive damage in composite materials and structures poses considerable challenges because damage is, in general, complex and involves multiple modes such as delamination, transverse cracking, fiber breakage, fiber pullout, etc. Clearly, damage in composites can be investigated at different length scales, ranging from the micromechanical to the macromechanical specimen and structur...
متن کاملApplication of Neural Networks to Damage Classification in Composite Structures
Smart classification software is designed to process data taken for damaged composite structures such as modern car bodies. This software is used in conjunction with Neural Networks algorithms to provide predictive models for impact damage in composite structures. The developed neural models correlates between various NDT testing techniques, such that in the absence of one technique, its result...
متن کاملUse of microfasteners to produce damage tolerant composite structures
The paper concerns the mechanical performance of continuous fibre/thermosetting polymer matrix composites reinforced in the through-thickness direction with fibrous or metallic rods or threads in order to mitigate against low delamination resistance. Specific illustrations of the effects of microfasteners in reducing delamination crack growth are made for Z-pinned and tufted composites. Respons...
