This robust benchtop device is designed to study stress and strain in a pressure filled, thin-walled cylinder. The cylinder, with narrow walls, is positioned between two support blocks, and internal pistons and seals are used to maintain oil sealing. The cylinder's end conditions can be adjusted from open to closed using a handwheel at one end. The device includes a hydraulic hand pump to regulate internal pressure, and an analogue pressure gauge displays the internal pressure. A pressure transducer provides feedback to the data acquisition interface and software. Strain gauges are attached to the exterior of the cylinder to measure radial and circumferential surface strain, and they can be positioned at various angles for accurate measurements.

Experimental Objective

Evaluate the behavior of Aluminum Alloy 6063 under both open-end and closed-end conditions.

Identify and determine the principal planes for each condition to understand the material's stress distribution and mechanical response.
