Buckling of unstiffened conical shells under combined loading – Experimental technique developed during a study of elastic buckling of conical shells under axial compression, torsion, and external or internal pressure is described, and test results are compared with linear theory
-
A simple testing technique for fracture under biaxial stresses – A mechanical-hydraulic machine for biaxial fatigue and ramp loading of precracked plate specimens is described. Preliminary results show that crack behavior in PMMA is independent of the stress acting parallel to the crack plane

Fracture control: Past, present and future – While maintaining the general theme of brittle and fast ductile fracture control in gas-pressurized pipelines, this lecture traces the development from empiricism through to an improved understanding of the relevant fracture dynamics, with the help of full-scale tests and laboratory model studies
-
Some results of testing simple structures under constant and variable loading during creep – Paper describes the results of some tests performed on rigs which have been constructed with a view to verifying the usefulness of the reference-stress concept
