Mechanical stresses in trees resulting from strain compatibility in an anisotropic material

Creator:: Lyons, Charles Kevin
Abstract:: Consider the bole of a tree to consist of a linear elastic material that is orthotropic with respect to the cylindrical coordinates. When the bole of a tree is subjected to resultant loads in the directions of the Cartesian base vectors, the S₁₁, S₂₂, S₃₃, and S₁₂ stresses in Cartesian...

Comparison of leg spring characteristics during running using mass-spring-damper modeling

Creator:: Watanatada, Pasakorn
Abstract:: During heel-toe running, the vertical ground reaction force (VGRF) profile has both impact and active peaks. Although the mass-spring model (a single mass and a linear spring) is simple and useful to predict running characteristics, its simulation of VGRF profiles produces only a single peak rather than the double peak...

Developing Design Model for Cellulose Nanocomposites

Creator:: Shir Mohammadi, Meisam
Abstract:: Today nano scale materials are being used for wide range of applications. One promising topic in nano scale materials is using them for reinforcement of different polymeric materials to reach desirable stiffness properties. The stiffness of these materials is mostly found experimentally because the nanocomposite community lacks a decent analytical...

Three-dimensional, nonlinear viscoelastic analysis of laminated composites : a finite element approach

Creator:: Wang, Min
Abstract:: Polymeric composites exhibit time-dependent behavior, which raises a concern about their long term durability and leads to a viscoelastic study of these materials. Linear viscoelastic analysis has been found to be inadequate because many polymers exhibit nonlinear viscoelastic behavior. Classical laminate theory is commonly used in the study of laminated...

Numerical modeling and experiments on wood-strand composites

Creator:: Le, Edward A.
Abstract:: In wood-based composites, the glue-line (interface) between wood-strands affects the stress transfer from one member to the next. The glue-line properties determine the rate of load transfer between phases and these properties depend on wood species, surface preparation, glue properties, glue penetration into wood cells, and moisture content of the...

A simplified dynamic model of the hind leg of a beetle during step initiation

Creator:: Mallysetty, Venkata Ramana
Abstract:: This thesis investigates a simple dynamic model of the hind leg of a beetle during initiation of a step. The primary assumption was that the full load of the body was carried on the hind leg during this time. That is, the only forces on the body were that of...
