This paper investigates the replacement of a conventional steel coil spring with composite disc aim minimizing its weight. Simulation in CAD system Siemens NX 12 was used to determine spring’s behavior. The regression functions were stated based on numerical simulation. Based solution minimum weight found using software programmed Matlab. prototype discs manufactured from carbon fibre pre...

The first results of multiple scattering simulations of polarized high-energy X-rays for Compton experiments using a new Monte Carlo program, MUSCAT, are presented. The program is developed to follow the restrictions of real experimental geometries. The new simulation algorithm uses not only well known photon splitting and interaction forcing methods but it is also upgraded with the new propaga...

Simulation of complex cloth-like visco-elastic materials is a hot topic today as more and more fields of application are discovered in research and industry. Theoretical foundations are needed to describe the non-linear physical properties of a material and to introduce its simulation with the desired accuracy and runtime characteristics. Particle based mass-spring models and semi-implicit inte...

Deployable structures made from ultrathin composite materials can be folded elastically and are able to selfdeploy by releasing the stored strain energy. This paper presents a detailed study of the folding and deployment of a tape-spring hingemade from a two-ply plain-weave laminate of carbon-fiber reinforced plastic. A particular version of this hinge was constructed, and its moment-rotation p...

This thesis is an investigation of the possibilities of realtime surgical simulation, specifically within the domain of congenital heart diseases. The problem domain of surgery on the heart of an infant is presented and the primary information necessary for a pre-operative surgical simulation tool is identified. Through cooperation with surgeons, domain specific abstractions and simplifications...

a new model is proposed for two-dimensional simulation of the concrete fracture in compression. the model generated by using the voronoi diagram method and with considering random shape and distribution of full graded aggregates at the mesoscopic level. the aggregates modeled by combining irregular polygons, which then is placed into the concrete with no intersection between them. by this new m...

In this paper we propose an e cient technique for the animation of exible objects Mass spring model was employed to represent the exible objects The easiest approach to animation with mass spring model is explicit Euler method but the explicit Euler method has serious disadvantage that it su ers from instability problem The implicit integration method is a possible solution to overcome the inst...
