I finished my bachelor in mechanical engineering this summer and I work as a development engineer. Thank you for sharing your knowledge - as I am already quite old (34) I am using your videos to not forget and refreshing my knowledge. I love mechanics and your videos :-)
Happy Christmas to you, kind Regards from Switzerland,
Lukas

Last post by Mark Barkey - April 21, 2022, 01:28:56 PMDepending on the element type, you should be able to set values for surface tractions (shear and normal stresses).

Last post by yasin - April 19, 2022, 08:23:50 AMHi everyone
I made a two-dimensional model in Abaqus. I want to define the lateral condition myself, that is, a state between plane strain and plane stress. Does Abaqus software have this capability?If it does, How?
Thanks for your help

Last post by Asish - February 19, 2022, 08:02:58 PMDear Professor,
My name is Kamanasish. Currently, I am pursuing my Ph.D. in the Dept. of Aerospace Engineering at the Indian Institute of Technology, Kharagpur, India. I am using Abaqus software for my research work. My area of interest is metal fatigue and damage in composite structures. Your video lectures on Metal Fatigue and Plasticity are just fantastic. Thanks a lot for sharing your knowledge.

Last post by Mark Barkey - January 06, 2022, 01:22:13 PMWelcome to the forum--
It sounds to me like you probably have some rigid body motion in your model. Something is likely taking off in space to infinity due to the applied force. It would have been held in place in displacement control.
You should be able to check by loading what results you have into a post processor--either ABAQUS CAE itself or something like Hypermesh.
That is all I can think of based on your description.
take care,
MEB
