Crack length measurement
I am trying to measure J - integral from experiment. " Let my initial fatigue crack length is 6mm, then i did single specimen unloading compliance test on it. The crack legth increased to 8mm" If i want to model the same geometry in FEA. Now my doubt is that "what carck length should i take 1) Initial fatigue crack = 6mm 2) final crack length = 8 mm.................... Note: I need to model my CT specimen in FEA to correct my experiments :-)

Eighty Years of Dislocation Theory and Work Hardening
On February 7, 1934, two consecutive papers by Sir Geoffrey Ingram Taylor were received and so the dislocation theory was born and the first attempt at describing work hardening was made. Before that date, it was known that there was a big gap between the ideal and the experimentally observed shear strength. While according to the calculations, the shear strength had to be of the order of one tenth (or with finer models one thirtieth) of the shear modulus, the measured shear strength was several orders of magnitude smaller. This large discrepancy brought about Geoffrey I.Taylor, Egon Orowan and Michael Polyani to independently postulate the existence of dislocations. Papers by Orowan and Polyani were published consecutively in one volume of Zeitschrift für Physik.
Caltech: secrets of the world’s number one university
Good International news on Caltech and engineering. Ares Rosakis, chair of the Division of Engineering and Applied Science,describes Caltech as “a unique species among universities…a very interesting phenomenon”.More can be found in the attachment or at the link below

instability induced by incoherent twin boundary in nanotwinned copper
1. Strain hardening and softening in nanotwinned Cu:
Nanotwinned Cu foils with about 99% coherent twin boundaries (TBs) among all the boundaries were made. These coherent
TBs, with an average spacing of 25 nm, were engineered approximately parallel to foil surfaces. Low plane-strain deformation
enhances the hardness by refining microstructure and introducing dislocations. High plane-strain deformation results in crystallographic
lattice rotation and reaction between dislocations and coherent TBs, and induces incoherent TBs, thus twin coarsening and
