Johnson Cook damage criterion for Alloy 718
Forums
Hi I'm looking for a Johnson Cook damage criterion for Alloy 718 (or Iconel 718) i.e. the constants (D1,D2,D3,D4,D5).
If anyone seen an article or book with these constants I would be thankful if you could help me out.
Thanks in advance
cohesive zone with curvature
Forums
Experts,
Anyone have experienece of curved cohesive zone model?
I just find people just use straight line cohesive zone geometry model.
Any difference between these two geometries?
Thanks.
cohesive zone model simulation :abaqus standard mode or explicit mode?
Forums
Since the available literature related to cohesive zone model simulation is done in abaqus standard mode, I'm curious if it is suitable to simulate in abaqus explicit mode.
Could you give me a suggestion?Thanks.
Hi, is it possible to include a cohesive zone with temperature dependence behavior in abaqus CAE

Hi
This is my first post so bear with me.
I have a question and an answer but have little idea how they got the answer. The question relates to a sample with load being applied at both ends.

mathematical equation for a crack in a ductile material
Forums
hi all,
im an engineering student...im doing a project on crack behaviour in a ductile material(mild steel) when a load is applied on it...im going to analyse it using ANSYS, for validating this i need a mathematical equation.....so plz if you have mathematical equations and journals regarding it plz reply me ...thank you...

Literature regarding the appearence of cracks in steel. Thermal, pressure fatigue
Forums
Choose a channel featured in the header of iMechanica
Hello!
I am wondering if anyone could recomend som literature for me to get my hands on.
If there is any literature regarding how the appereance of a crack in a piece of thin metal (~0,5mm - 1 mm) could be related to pressure fatigue or thermal fatigue.
Does the crack due to thermal fatigue have a specific appereance and so on. I need get my hands on practical pictures and so on, not equations.
Are there any signs in the vicinity of the crack that is indicating that this could be due to pressure fatigue.
Any help is much appreciated.
3D modelling of an ellliptical crack in ANSYS
Forums
Free Tags
I am a beginner in FEM and just started using ANSYS. I need to study the stresses and SIF at the crack front of an elliptical crack inside a material subjected to a stress perpendicular to the crack plane. Any details on how I should build my model?
What is the easiest way to define a cracked area, and crack front and then mesh it
How can i merge together a cracked area and an unmeshed area?
I found a lot of links and articles that states they did it, but none explained the procedure do do it.
Thanks
