Localized deformation and randomly shaped imperfections are salient features of buckling-type instabilities in thin-walled load-bearing structures. However, it is generally agreed that their complex ...

This repository contains the codebase for the numerical implementation of the Galerkin method (GM) for the buckling and post-buckling analyses of clamped-clamped cylindrical shells under combined ...

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 ...

Functionally graded shell structures combine spatially varying material properties with curved geometries to achieve tailored strength, stiffness and stability characteristics. These shells often ...

In the present study, a hybrid ?nite element method is applied to investigate the dynamic behavior of a spherical shell partially filled with fluid and subjected to external supersonic airflow. The ...

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 ...

ABSTRACT: In the present study, a hybrid ?nite element method is applied to investigate the dynamic behavior of a spherical shell partially filled with fluid and subjected to external supersonic ...

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 ...

Origami-inspired mechanisms can transform flexible sheets into lightweight and efficient structures. Inspired by curved-crease origami, here, we design a deployable tubular structure featuring ...

HUNTSVILLE, Alabama - NASA engineers improvised in Huntsville on Wednesday when their carefully planned - and televised - "can crush" experiment didn't crush a rocket shell as expected. But improvise ...
