Roberto Ballarini, University of Houston Thomas and Laura Hsu Professor and department chair of Civil and Environmental Engineering, is leading the effort to predict the detrimental effects of ...

Negative stiffness honeycombs are a hexagonal cell structure that turns soft under pressure, but then resumes its resiliency without internal breakage. Share on Facebook (opens in a new window) Share ...

The NABUCCO project aims to develop radically new concepts of adaptive and buckling-driven composite structures for next generation aircraft. In aeronautics, buckling is generally avoided because it ...

Shell structures—thin, curved elements such as cylinders, spheres and domes—are prized for their high strength-to-weight ratio but are exceptionally sensitive to buckling instabilities. Even minute ...

The nonlinear buckling behaviour of composite structures encapsulates the intricate interplay between geometry, material anisotropy and post-critical response when these systems are loaded beyond ...

Buckling Restrained Braces application to provide more resilient bridges have been subjected to cyclic displacement histories representative of yearly thermal demands and of earthquake excitations.

Linear finite-element analysis does not provide enough information about buckling to make correct design decisions, especially when designing lightweight components ...

Engineers looked to nature to find a shape that could improve all kinds of slender structures, from building columns to bicycle spokes -- they found an answer in sea sponges. Judging by their name ...

Research areas: Computational Mechanics, Finite Element Method, Mesh-free Methods, Extended Finite Element Method, Multi-scale Analysis, Nonlinear Structural Mechanics, Thin-walled and Composite ...

An engineer has designed a model to guide better design of thin-walled structures, like planes, cars and submersibles, to avoid catastrophe like sudden collapse due to buckling. A University of ...
