Reconciling Elastic and Equilibrium Methods for Static Analysis

This paper examines two widely used classes of methods for static analysis of masonry buildings (linear elasticity analysis using finite elements and equilibrium methods), provides a systematic explanation for the discrepancy observed between the two methods, and presents a unified formulation of the two approaches.

Computational Design of Stable Planar-Rod Structures

This computational method for designing and fabricating stable, easily assemblable wire sculptures consisting of interlocking wires relies on elasticity and frictional contact to achieve stability and represents an extremely efficient alternative for low-fidelity rapid prototyping.
