Zn/Cu regulated critical strain and serrated flow behavior in Al–Mg alloys

Materials Science & Engineering: A, 2020
Next-generation high performance aluminum alloys are required for lightweight strategies and advanced automotive applications. A current challenge for 5xxx series alloys is their poor strength and dreadful surface appearance caused by serrated yielding ...

Inelasticity increases the critical strain for the onset of creases on hydrogels

, 2020
When a soft material (gel, elastomer, or biological tissue) is compressed beyond a critical strain, its smooth surface forms creases. During this process, a material particle near a crease undergoes a path of load and unload.

Prediction of critical strains and critical support pressures for circular tunnel excavated in strain-softening rock mass

Engineering Geology, 2017
Abstract The critical strain is a strain level at the tunnel periphery beyond which the instability and squeezing problems are likely to occur, thereby it provides helpful guide to assess the tunnel stability. Among the current studies for predicting the critical strain, the influence factors such as the required support pressure, the strain ...

Influence of the solidification path of AlMgSi aluminium alloys on the critical strain rate during remote laser beam welding

Science and technology of welding and joining, 2019
The solidification paths of aluminium alloys have a major influence on the susceptibility to hot cracking during laser beam welding. The model of Rappaz, Drezet and Gremaud allows to predict the susceptibility to hot cracking of an alloy as a function of

Strain and critical thickness

2000
Consider an epilayer of a semiconductor with lattice constant al} grown on a thick substrate with lattice constant asub} (illustrated in Fig. 3.1). The lattice mismatch is measured by the misfit parameter fm} defined below [3, 235]

Critical behavior of a strain percolation model for metals

Physical Review E, 2002
Extensive simulations of a strain percolation model for a deforming metal have been performed to examine its strain behavior. We find that the total strain exhibits critical power-law behavior that is well explained by two-dimensional percolation theory.

Critical Strain for Shish-Kebab Formation

Macromolecules, 2009
A combination of extensional rheological and in situ synchrotron radiation small-angle X-ray scattering (SR-SAXS) measurements was introduced to investigate critical strain e* for shish formation and validate whether coil−stretch transition or stretched-network is responsible for shish-kebab formation in high density polyethylene melt.

A Strained Criticism of Wave Theory

Terrorism and Political Violence, 2015
In the deepest depths of my Cold War childhood, I recall asking my father “what is Communism?” It was in school, on television, in comic books, and on the radio.
