10105 CFRPアングルプライ積層板におけるマトリックスクラッキングの解析(疲労およびき裂進展,OS10 先進材料の力学と強度)
詳細
Matrix cracking initiation and development in CFRP angle-ply laminates under tensile loading are evaluated experimentally. Soft X-ray radiography is used to detect matrix cracks. Effect of ply thicknesses on matrix cracking is discussed. Matrix crack density is measured as a function of applied laminate stress. To discuss the experimental results, a stress analysis procedure considering the material nonlinearity is employed.
