We present experiments on the dynamic buckling and fragmentation of slender rods axially impacted by a projectile. By combining the results of Saint-Venant and elastic beam theory, we derive a preferred wavelength lambda for the buckling instability, and experimentally verify the resulting scaling law for a range of materials including teflon, dry pasta, glass, and steel. For brittle materials,...

Despite the popularity of a completely free beam resting on tensionless foundation in construction industry, existing bending analysis solutions are limited to certain types loads (mostly point and uniformly distributed loads); these also quite complex for practicing engineers handle. To overcome associated complexity, simple iterative procedure is developed this study, which uses Ritz method f...

Buckling and post-buckling thermomechanical deformations of a functionally graded material (FGM) Timoshenko beam resting on a two-parameter nonlinear elastic foundation and subjected to only a temperature rise have been numerically investigated with the shooting method. The material properties are assumed to vary only in the thickness direction according to a power law function. Through-the-thi...
