Interpreting load paths and stress trajectories in elasticity

D.W. Kelly, M.W. Tosh

Design engineers use the term load path to describe, in general terms, the way in which loads path through a structure from the points of application to the points where they are…

Contact problems in the design of a superconducting quadrupole prototype

Claude Blanzé, Laurent Champaney, Pierre Vedrine

This paper focuses on the design of a superconducting quadrupole prototype. This structure includes many frictional contact zones, and the loading conditions are complex…

Explicit preconditioned conjugate gradient schemes for solving biharmonic equations

George A. Gravvanis

A new class of explicit preconditioning methods based on the concept of sparse approximate factorization procedures and inverse matrix techniques is introduced for solving…

The visualization of electric force lines in two‐dimensional electric field computation

Xiang Cui

An algorithm for the visualization of the electric force lines is discussed. Based on the nodal potentials calculated by the conventional finite element method, the boundary…

A local optimisation method for obtaining material model parameters

Duncan Macdougall, Nikica Petrinic

A local optimisation method for obtaining material parameters in finite element simulations has been developed. The method is based on the minimisation of an error function which…
