3D lattice model for post-yield and fracture behaviour of timber. (2008)
Journal Article
Reichert, T., & Ridley-Ellis, D. (2008). 3D lattice model for post-yield and fracture behaviour of timber. Timber Engineering,

The paper describes the development of a bespoke Finite Element program to model timber with a three dimensional lattice of single spring elements. These springs mimic meso-scale timber behaviour, namely the crushing and separation of fibre bunches b... Read More about 3D lattice model for post-yield and fracture behaviour of timber..

Formed from a thick layer of polystyrene foam sandwiched between two layers of oriented strand board, structural insulated panels (SIPs) are a viable alternative to traditional wood stud shear walls. Developed in North America, SIPs satisfy building... Read More about Racking Performance of Structural Insulated Panels.

Geometric Non-Linear Behaviour of Single Shear Bolted Joints. (2006)
Journal Article
Reichert, T., & Ridley-Ellis, D. (2006). Geometric Non-Linear Behaviour of Single Shear Bolted Joints. Timber Engineering,

Findings are presented of the first stage of an investigation of second-order effects that influence the resistance and stiffness of single shear bolted joints. These effects develop as a result of joint deformation and the rotation of all, or part,... Read More about Geometric Non-Linear Behaviour of Single Shear Bolted Joints..

Timber Plate Dynamics with Space-Time Finite Element (2006)
Journal Article
