ジャーナル フリーThe energy absorption of a polymer particle to dynamic loads is discussed based on the linear theory of elastodynamics. Assuming incident waves, P and SV-waves, as the dynamic loads, the strain energy stored in the particle is obtained in graphical forms. It is shown that the ability of the energy absorption in the practical range is governed by the mode of circumferential deformation of the particle, when the frequency of the incident wave is lower. For the load of the incident P-wave, the zeroth mode of all round tension and compression of the particle deformation is the best deformation for absorbing the energy, however, for that of SV-wave, the second mode of elliptical deformation is the best.抄録全体を表示PDF形式でダウンロード (739K) -

ジャーナル フリーThe energy absorption of a polymer particle due to the dynamic load of SH-wave is discussed based on the linear theory of elastodynamics. It is shown that the ability of the energy absorption in the range of the practical use is governed by the deformation mode of the particle, when the frequency of the incident wave is lower. It is shown that the first mode of the circumferential deformation is the best for absorbing energy in the particle. The present and previous papers completes the discussion on the energy absorption in a polymer particle for the three types of the dynamic loading.抄録全体を表示PDF形式でダウンロード (529K) -

ジャーナル フリーThe mechanical in-plane shear testing method for unidirectional CFRP panels has not yet been authorized internationally because of its difficulty in obtaining the uniform shear stress field. A revised picture-frame fixture was proposed to obtain the essential in-plane shear properties along fibers in the previous paper, but the specimen configuration included curved corners which exhibit stress concentration. In the present paper, an attempt was offered to simplify the specimen configuration in order to obtain more uniform shear stress distribution than as seen in the previous specimens which were used in the picture frame fixture. Furthermore, another proposal was offered where the fiber direction was changed perpendicularly in rail shear methods. The experiments on unidirectional CFRP specimens together with the numerical FEM analyses were carried out in order to verify the advantages of such revisions by which the higher true shear strengths were obtained without stress concentration.抄録全体を表示PDF形式でダウンロード (648K) -
