Novel stiffeners exploiting internal pressurisation to enhance buckling behaviour under bending loads

Behaviour of Human Femur Bone Under Bending and Impact Loads

Femoral fractures are among the most common major injuries that an orthopedic surgeon will be required to treat. During fracture treatment of femur bone the biomaterials are used for fracture healing. Evaluation of femur fractures using clinical data is confounded by multiple patient and fracture specific factors making it difficult to draw meaningful conclusions, despite the inclusion of large...

Monotonicity of Buckling Loads under Symmetrization

Viscoelastic behaviour of a polyester resin concrete reinforced with non- metallic bars under bending loads

This paper deals with the study of a highly durable polyester polymer concrete reinforced with glass fibre reinforced polymer rebars. The paper describes the properties of this specific concrete, which were tested using different experimental techniques such as porosimetry, scanning electron microscopy and petrography. Likewise, characterisation in a macro-scale was carried out to define the me...

Elastocapillary instability under partial wetting conditions: bending versus buckling.

The elastocapillary instability of a flexible plate plunged in a liquid bath is analyzed theoretically. We show that the plate can bend due to two separate destabilizing mechanisms, when the liquid is partially wetting the solid. For contact angles θ(e) > π/2, the capillary forces acting tangential to the surface are compressing the plate and can induce a classical buckling instability. However...

Pipes under Internal Pressure and Bending

This article covers the general behaviour of a straight uniform pipe, with built-in open ends, subject to internal pressure and in plane bending or curvature. It is intended as a summary of the basic equations driving the unintuitive phenomena of bending and instability of pipes under internal pressure. The analysis covers in addition the investigation of opposite pressure stabilisation effects...
