Mechanisms Of Fracturing In Structures Built From Topologically Interlocked Blocks (2004)
Khor, H. C., Dyskin, A. V., Estrin, Y., Pasternak, E.
Failure of materials is in many cases associated with initiation and subsequent propagation of macroscopic fractures. Consequently, in order to increase the strength, one needs to inhibit either...

Continuous and Cyclic Stress Relaxation in Aluminium. (1998)
Quadfasel, U., Mecking, H., Estrin, Y.
The stress relaxation behavior of aluminum (99.99%) was investigated at three temperatures (295, 363 and 433 K); in addition to the customary experimental procedure, by which the total strain of the...
Discontinuous Yielding in an Al-Li-Zr Alloy. (1998)
Kubin, L. P., Styczynski, A., Estrin, Y.
Discontinuous yielding in an Al-2.25Li-0.9Zr alloy has been studied. Tensile tests were conducted at room temperature at strain rates ranging from 1.25 x 10(-5)/s to 1.25 x 10(-2)/s. Discontinuous...
Steady State Behaviour of Alloy 800H Under Cyclic Deformation. (1998)
The steady state mechanical response of alloy 800h undergoing strain controlled fatigue tests was studied. Data was used to fit an equation relating strain rate/amplitude and the steady state stress....
