The biomechanical properties of soft tissue derived from experimental measurements are critical for developing a reality-based model for minimally invasive surgical training and simulation. In our research, we focus on developing a biomechanical model of the liver under large tissue deformation. This paper presents the experimental apparatus, experimental data, and formulations to model the exp...

Abstract In this paper, a multi-physics field coupled finite element model for the motion of projectile in hot barrel is proposed and validated by muzzle velocity test temperature test. The includes heat transfer analysis, explicit dynamic analysis investigates in-bore under different conditions. It pointed out that, with increase temperature, radial displacement centroid increases, consistency...

Application of impact energy absorption systems in different industries is of special significance. Thin-walled tubes, due to their lightness, high energy absorption capacity, long crushing length and the high ratio of energy absorption to weight, have found ever-increasing application as one of the most effective energy absorption systems. In this research, through  carrying out experimental t...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

the present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (prb), with their reduced forms. the two most frequently used mechanisms of methane combustion (gri3.0 and miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. while the findings of numerical simulation of prb show fi...

Taking a large-caliber gun as the research object, projectile and coupling finite element numerical simulation model during extrusion process is established according to technology. The dynamic of carried out by using ABAQUS/EXPLAICT solver, stress variation law belt groove barrel obtained. In post-processing module software, data displacement, velocity acceleration at center mass in are extrac...

Abstract To realize the requirements of precision probe for translational guidance compliant mechanism, expression movement screw parallelogram guide mechanism is proposed. The flexibility matrix used to study influence geometric structure and size flexible units on performance finite element analysis simulation. results show that model in good agreement with simulation results, maximum relativ...

concrete deformation due to temperature and moisture condition will always develop simultaneously and interactively. the environmentally (hygral and thermally) induced stress and deformation are essential to concrete durability. to simulate the deformation of concrete caused by the coupling effect of temperature and moisture, a numerical simulation approach is proposed comprising analytical pro...

This paper proposes a new sliding mode control (SMC)  based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...
