Thin Cylinder

Bench‐mounted machine to allow students to do stress and strain tests on a thin‐walled
cylinder
Experiments
Investigations into stresses and strains in a thin cylinder, to give students an understanding of:
Longitudinal stress, hoop (or circumferential) stress, radial stress and biaxial stress
The behaviour of the cylinder under both open and closed‐end conditions
The use of strain gauges
The stress strain relationship and value of Young’s modulus for the cylinder material
Indirect strain and stress
The value of Poisson’s ratio for the cylinder material
The use of Mohr’s circle to calculate the shear strain at any position in the cylinder
The use of the ‘superposition method’ to find the principal strains

The effect of the biaxial stress system
Sources of error in their experiments
Specifications
To include a thin‐walled aged aluminium alloy 6063 thin cylinder and hydraulic hand pump
with electronic pressure transducer, mounted on precision engineered steel base unit
To include a clamp at each end of the cylinder and a hand wheel, allowing open and closed
ends experiments
