hi am doing my project on high speed machining of aluminium and steel. for chip propagation i want some procedure how to do crack/fracture analysis using ABAQUS. if anybody knew about this please send me information regarding steps involved in building crack propagation.if any practile examples or tutorials are available for this send me to my mail id. my mail id is sasivamsi [at] gmail.com. am using ABAQUS V6.6.
Hi, everyone,
I am new here. Now I am doing a research which is related to the Euler's buckling formula. It is known that when the cylinder is thick enough, Euler's buckling formula is no longer valid. I want to know in which region of slenderness(aspect ratio) of a cylinder or column that the Euler's buckling formula is valid. Is there any analytical study or numerical results about it? Is there any suggestion or paper I can find?
Thank you very much!
The fractal crack model described here incorporates the essential
features of the fractal view of fracture, the basic concepts of
the LEFM model, the concepts contained within the
Barenblatt-Dugdale cohesive crack model and the quantized
(discrete or finite) fracture mechanics assumptions. The
well-known entities such as the stress intensity factor and the
Barenblatt cohesion modulus, which is a measure of material
toughness, have been re-defined to accommodate the fractal view of
fracture.
The Department of Aerospace Engineering at Iowa State University invites applications for multiple tenure-track faculty positions at the assistant, associate, or full professor ranks to begin August 2009.
