Multi-field Modelling of Cosserat solids

STRANDS: Interactive Simulation of Thin Solids using Cosserat Models

STRANDS are thin elastic solids that are visually well approximated as smooth curves, and yet possess essential physical behaviors characteristic of solid objects such as twisting. Common examples in computer graphics include: sutures, catheters, and tendons in surgical simulation; hairs, ropes, and vegetation in animation. Physical models based on spring meshes or 3D finite elements for such t...

Computational Cosserat Dynamics in MEMS Component Modelling

The modelling strategy and simulation of flexible components of MEMS are addressed in this article. A newly developed Cosserat Rod Element (CRE) approach is employed to model the nonlinear dynamic equations of motion for micro resonators. Models constructed using this approach seek to capture the most significant characteristics of a microstructure in a few variables governed by a few ordinary ...

Modelling methodology of MEMS structures based on Cosserat theory

Modelling MEMS involves a variety of software tools that deal with the analysis of complex geometrical structures and the assessment of various interactions among different energy domains and components. Moreover, the MEMS market is growing very fast, but surprisingly, there is a paucity of modelling and simulation methodology for precise performance verification of MEMS products in the nonline...

Discrete Cosserat Approach for Multi-Section Soft Robots Dynamics

In spite of recent progress, soft robotics still suffers from a lack of unified modeling framework. Nowadays, the most adopted model for the design and control of soft robots is the piece-wise constant curvature model, with its consolidated benefits and drawbacks. In this work, an alternative model for multisection soft robots dynamics is presented based on a discrete Cosserat approach, which, ...
