Mathematics of stable tensegrities

Most tensegrities built today are based on usage of elastic string. Such tensegrities are unstable and are merely art. This work proposes a general methodology for design of stable tensegrities based on inextensible cables. The method also allows design of tensegrities with designable softness. Such stable tensegrities find significant applications in space structures.

A study of contact methods in the application of large deformation dynamics in self-contact beam

This work introduces a procedure to analyze contact dynamics of beams undergoing large overall motion including large deformations and self-contact situations. The contact search task presented here aims to detect the contact events using an algorithm based on intersection of the oriented bounding boxes (OBBs) approach.

A finite element for soft tissue deformation based on absolute nodal coordinate formulation

This paper introduces an implementation of the absolute nodal coordinate formulation (ANCF) that can be used to model fibrous soft tissue in cases of three-dimensional elasticity. It is validated against results from existing incompressible material models. The relevance of the implementation to the modeling of biological tissues is discussed and results are compared with Ansys.

Modeling of two-body abrasive wear of filled elastomers as a contact-induced fracture process

This work presents a first non-traditional approach to modeling two-body abrasive wear due to the contact between elastomeric tire compounds and road surfaces. The process of two-body abrasion between rubber and surface is modeled as a multiscale contact-fracture process. Cracks are initiated and grow due to contact stresses leading to substantial wear.

Model reduction in thin-walled open-section composite beams using variational asymptotic method. Part I Theory

This work describes the development of a comprehensive and reliable tool for analysis of the most commonly used geometries of thin-walled, open-section composite beams. Here, we propose an asymptotically-correct reduced order model using the Variational Asymptotic Method (VAM), to study the nonlinear and non-classical effects observed in anisotropic beams.

Mesoscale constitutive modeling of non-crystallizing filled elastomers

We develop a multiphase constitutive model at the mesoscale explicitly considering filler particle aggregates, elastomeric matrix and their mechanical interaction through an approximate interface layer. The developed constitutive model is used to demonstrate cluster breakage, as one of the possible sources for Mullins effect observed in non-crystallizing filled elastomers.

A Poroelastic Element for FEAP Using AceGen

The error free generation of elements for complex field equations can be helped via the judicious use of automated systems. In this work, we use AceGen for automated generation of transient linear poroelastic elements for FEAP.

Strategies to apply soil models directly as friction laws in soil-structure interactions

In this work three different concepts for a direct application of soil models within a frictional contact description are developed. These concepts can be used in conjunction with all different kinds of contact formulations and solution methods.
