Mass-Spring Simulation using Adaptive Non-Active Points

Application of molecular modeling with mass-spring systems for computer simulation and animation

This paper demonstrates the use of potential functions of molecular modeling in mass-spring systems. In mass-spring systems, force acting on each mass point is determined by the spring length between linked mass-points. In molecular modeling, forces are calculated using bond length (spring length), bond angle and stretch-bond interactions. Molecular modeling therefore provides more accurate for...

Using the Adaptive Frequency Nonlinear Oscillator for Earning an Energy Efficient Motion Pattern in a Leg- Like Stretchable Pendulum by Exploiting the Resonant Mode

In this paper we investigate a biological framework to generate and adapt a motion pattern so that can be energy efficient. In fact, the motion pattern in legged animals and human emerges among interaction between a central pattern generator neural network called CPG and the musculoskeletal system. Here, we model this neuro - musculoskeletal system by means of a leg - like mechanical system cal...

Buckling of Laminates with Multiple Through-the-Width Delaminations Using Spring Simulation Model

Delamination is one of the most common failure modes in composite structures. In particular, when the laminated composites are subjected to compressive loads, delamination becomes a constraint in the design process. In this study, the system is modeled as a plate supported by an elastic foundation. The elastic adhesive layer between the buckled sublaminates is represented by some parallel sprin...

Modeling the feeding process in gill-box using non-linear mass-spring system

Spring-mass model application to engineering NURBS surface reconstruction

In this paper an original application of spring-mass based model to NURBS surface reconstruction from point clouds is described. In last few years spring-mass models have been largely and successfully applied in Computer Animation for cloth simulation, but their application has been limited to non-Engineering fields. Following the physical metaphor of laying a cloth over a non-structured set of...
