Strength and properties of materials > Stress and strain





This equipment is used for studying the stresses in a thin wall cylinder.

A thin wall aluminum alloy cylinder is mounted on a rigid steel frame. Internal pressure is applied to the cylinder by means of a hydraulic hand pump with oil reservoir. Pressure in the cylinder is indicated on a pressure gauge. A screw is attached on a frame to open or close one side of the cylinder. When the cylinder is open, only circumferential stress occurs on the cylinder. When the cylinder is closed, both circumferential and axial stresses occur.

Strain gauges are of the same gauge factor and the gauges are fixed onto the cylinder at different angles. Each strain gauge is wired to form a full bridge with temperature compensation gauge and zero adjustment in a bridge box with strain gauge indicator.

Instruction manual is also included.
