A theoretical and experimental assessment is made of the optimum design of short composite (duplex) cylinders based on the Mohr criterion of failure—a criterion for which the degrees of brittleness of the materials of construction can be taken into account. The design data are presented in the form of governing equations which define optimum design. The use of different materials for the cylinder components is considered.
Experiments performed on a number of duplex cylinders made from different materials having differing degrees of ductility confirm the reliability of the Mohr criterion for this type of design.
