The purpose of this work is developing the injury analysis model that can be expressed liver damage state by the Moving Particle Semi-implicit (MPS) method. In this paper, we set the material properties of the liver by simulating material test usi...

With regard to the out-of-plane bending energy of an elastic surface membrane, capsule deformation was compared between Helfrich's isotropic continuum model and discrete models using a triangulated surface. The in-plane deformation of the membrane...

Direct numerical simulations of the mechanics of a single red blood cell (RBC) were performed by considering the nonuniform natural state of the elastic membrane. A RBC was modeled as an incompressible viscous fluid encapsulated by an elastic memb...
In car accidents abdominal organ injuries are frequently caused by seat belts which induce compression to the abdomen. Therefore much attention has been paid to reducing the injuries caused by the protection device. Accordingly there is a need for...
We performed a computer simulation for effects of an anticoagulant agent on thrombus formation under the influence of the blood flow, assuming a rat arteriovenous shunt in which a nylon filament was inserted. A blood model consisted of a normal bl...
A backward facing step flow was numerically simulated in two dimensions using a differential model of the LSMPS method which is a higher-order version of the MPS method, aiming at a highly accurate fluid analysis in a particle method simulation of...
A clot of enzyme-activated milk in a low flow region was observed as a model of a venous thrombus. The milk was perfused in a micro channel with a custom made perfusion system A wall shear rate was controlled in the range of 10 to 22500 s^<-1>. A ...
