ジャーナル フリーDamage identification methods using vibration data have attracted attention as health monitoring systems of composite laminated structures. In many papers referred to damage identification methods using vibration data, damage is modeled in stiffness degradation regardless of damage modes. In health monitoring of real structures, identifying size and location of slight delamination, which accompany matrix cracks, is important. However, the relationship between the change of natural frequency caused by stiffness degradation and those caused by actual delamination is unknown. Then, unconfirmed applicability of damage identification method with stiffness degradation model to identifying delamination would be introduced. In the present study, the relationship between stiffness degradation and delamination is investigated in terms of factors that control the natural frequency changes of the structures by using FEM. Applicability of damage identification method to delamination identification is also examined.抄録全体を表示PDF形式でダウンロード (6858K) -

ジャーナル フリーMeasuring method for CTE (coefficient of thermal expansion) of honeycomb sandwich panels with face sheets made of polymer matrix composite was studied. At first, the optimum size of specimens for an accurate measurement was calculated by using the finite element method. Then, based on the results of the calculation, a CTE measuring system was developed utilizing photoelectric displacement sensors. The accuracy of the system was evaluated employing zero-expansive glass and carbon fiber reinforced plastic as a reference material whose CTE is estimated with an accuracy of 0.01×10-6/K. As the result, the system was found to have an accuracy of 0.1×10-6/K or better. Furthermore, measuring error of commercially available delatometer that employs a smaller size specimen was studied. The finite element analysis and the experimental study indicated that the error in that conventional measurement is approximately 0.2×10-6/K.抄録全体を表示PDF形式でダウンロード (9946K) -
