Competitive Inhibition of Mammalian Hyaluronidase by Tomato Saponin, Esculeoside A

Autor: Jian-Rong Zhou, Souta Kimura, Kazumi Yokomizo, Toshihiro Nohara

Publikováno v: Natural Product Communications. 13:1934578X1801301

Esculeoside A, a glycoside of spirosolane-type, is identified as a major component in ripe tomato fruits. Our previous study showed that esculeoside A inhibited hyaluronidase activity in vitro and ameliorated experimental dermatitis in vivo. The aim

Mixed-Mode Interfacial Debonding Simulation in Single-Fiber Composite under a Transverse Load

Autor: Souta Kimura, Pranav D. Shah, Jun Koyanagi, Sung Kyu Ha, Hiroyuki Kawada

Publikováno v: Journal of Solid Mechanics and Materials Engineering. 3(5):796-806

Due to the coupling between the opening and sliding modes of an interfacial crack between a fiber and matrix, measuring the individual values of the interfacial strengths, specifically the normal and shear strengths, is very difficult. A method based

Evaluation of the Interfacial Properties in Polymer Matrix Composite: Experiments and Elasto-Plastic Shear-Lag Analysis

Autor: Jun Koyanagi, Souta Kimura, Takayuki Hama, Hiroyuki Kawada

Publikováno v: Key Engineering Materials. :167-172

An energy-based analysis has been developed to evaluate interfacial adhesion between fiber and matrix in a single fiber composite over the years. However, the value of the energy-based parameter, e.g. an energy release rate, depends on a stress distr

An Improved Shear-Lag Model for a Single Fiber Composite with a Ductile Matrix

Autor: Hiroyuki Kawada, Jun Koyanagi, Souta Kimura, Takayuki Hama

Publikováno v: Key Engineering Materials. :333-336

A shear-lag model is developed to predict the stress distributions in and around an isolated fiber in a single-fiber polymer matrix composite (PMC) subjected to uniaxial tensile loading and unloading along the fiber direction. The matrix is assumed t

Evaluation of Initiation of the Interfacial Debonding in Single Fiber Composite (Energy Balance Method Considering an Energy Dissipation of the Plastic Deformation)

Autor: Jun Koyanagi, Souta Kimura, Hiroyuki Kawada

Publikováno v: JSME International Journal Series A. 49:451-457

Fiber-matrix interfacial adhesion in composites is traditionally evaluated by means of a stress-based parameter. Recently, an interfacial energy parameter is suggested to be a valid alternative. However, the energy-based approaches overestimated the

Energy absorption of crashworthy structure for rolling stock of a railway

Autor: Takashi Yamaguchi, H. Nakamura, Souta Kimura, T. Mochida, T. Kawasaki

The energy absorptions of crashworthy structures composed of welded aluminium alloys were evaluated using finite element analysis (FEA). In the FEA, a damage-mechanics model was employed as a material model for the parent aluminium alloys and the wel

Numerical Evaluation of Energy Absorption of Crashworthy Structure for Railway’s Rolling Stock: Application of Damage Mechanics Model

Autor: Takashi Yamaguchi, Souta Kimura, Toshihiko Mochida, Hideyuki Nakamura, Takeshi Kawasaki

Publikováno v: Volume 9: Transportation Systems; Safety Engineering, Risk Analysis and Reliability Methods; Applied Stochastic Optimization, Uncertainty and Probability.

The energy absorption of a crashworthy structure for railway’s rolling stock was studied experimentally and numerically. A quasi-static compression test was conducted using a full-scale mockup of a crashworthy structure constructed with welded alum
