Thank you :)

I used instead of Offset feature, the Thicken feature. It worked good. Insert ---> Offset/Scale ---> Thicken. But at the same time, could you please Mr. Toost attach here the NX file which you modified. Thank you.

Yes it is changing, try to increase and decrease the Offset..

Here is the file. The airfoil now has a certain twist. Why when I want to increase the Offset value (which is minimum now is 0.06 mm), the twist will not show as original ? For example, I want the Offset to be +1.5 mm with same...

Hello, can I twist a solid body in NX 8.5 ? Actually, first I had a sketch where I swept it along a helix. After that I used the Draft option but unfortunately the body is no more twisted as it was(it's an airfoil). Can I know twist it again ??

Hey all, Thank you for your responses. Yes, I am using tet elements for my mesh. Here is a picture as a print screen from a book says that: For Brittle materials: If the Maximum Principle Stress reaches the Fracture Strength (TRS) of the material, it will fail. So, I'll use it...

Attached is a picture of the mesh and position of the group of nodal forces applied as a big nodal force (Not to have a concentrated stress if I apply 1 single nodal force). Second, I don't have a yield value in the data sheet. Instead I have the TRS value and K1C and...

Here is picture 2 (Von Mises) I applied a force of 3500 N.http://files.engineering.com/getfile.aspx?folder=1bd3d528-62e3-419f-99ba-e35da064f9ba&file=Von_Mises_1.jpg

Attached is the first picture of the results I got. (Maximum Principle Stress). Note: TRS value is 3078 MPa while the Von Mises is 17350 MPa !!!!!!!! As you see, it's a huge difference !!! So, can I compare the Max Principle Stress with the TRS and ignore the Von Mises ...

What is the difference between Von Mises and maximum Principal stress ? I have a Brittle material (WC-10% Co), and I would like to see when it fractures. I have Transverse Rupture Strength value (3700 MPa). Can I compare the Max Priciple Stress with TRS with ignoring Von Mises ?? I am using...

I want only to check where failure may occur without seeing the failure behavior and how the crack propagates. Only analysis through the contour colors. Besides, I have the Transverse Rapture Strength (TRS) value (3700MPa), Poisons ration, elastic modulus and K1C only. Can I compare TRS with...

The thing is, I don't know the value of the force. That's why I am using FEM to know what maximum force I can apply on the tool before breakage. I tried to apply a force on a bigger area (many nodes together) as attached below. Are the results logical ...

My model is so easy. Isotropic Elasticity model using tungsten carbide cobalt as a material. Applying a radial force near the tip of the tool while fixing the clamp. My question now, can I use a Moment instead of the force ?

Sorry, I can't get you exactly what you mean. Can I use a Moment instead of a force ? Would it solve the problem and give good results ?

I tried to increase the area but unfortunately it didn't work. By the way, I am using Tungsten carbide cobalt (10%) as a material.

Hey, I got a problem with stress concentration after I applied a point force. The tool has a fixed support at the half of the shank approximately. Attached is a pic about the problem. How to approach to fix that...
