So i solved the above problem. I had forgotten to change the contact settings from "Standard" to "Bonded (always)" in the contact wizard.
However, that didnt solve my problem as i was still getting large errors. So i thought i would do a test to see if it was my contact settings. I had...
Have been using ANSYS Mechanical to conduct some analyses, but am now moving to ANSYS APDL to investigate the effectiveness of Solid-Shell elements.
However, I've run into a problem. I can't figure out how to apply a load to an area!
I have been playing around with the SURF154...
I have been using both ANSYS APDL and ANSYS Workbench (Mechanical) to run analysis on a structure. After loading the structure, in Mechanical i was able to scope my results for deformation and EQUIV stress to just the adhesive layer as this is what im interested in.
However, I can't...
I created the model in SolidEdge and saved it as an iges file. Then using Workbench, i set up a Mechanical APDL module and assigned the iges model to it. Then i can right click and say "edit in Mechanical APDL" and it will start up ANSYS classic for me to do my meshing, add loads etc...
Simulating "Bonded Contact" from ANSYS Mechanical in ANSYS APDL
Im looking into the accuracy of using different element types to model a particular structure. As a simple approximation think of it as a beam split into 3 horizontal sections. Shown in the diagram as top, middle & bottom...
I have been given the following load-displacement plots for the same specimin with two different crack lengths. The lines are identical up to a load od 750N
i need to calculate the area of the blue shaded region to obtain a value of Jc using a separate equation...
Given two wires of guage length 100mm and 200mm
They are loaded to fracture in tension
The 100mm sample extends by 15mm
The 200mm sample extends by 25mm.
I need to use this information to calculate the nominal strain at which necking commences in the wires
Ahh i see. Yes i understand that. I can explain the yield graph very well now, thanks for your help. Really Appreciate it.
Finally for the fracture toughness graph. Do i apply the same information about dislocations being less likely to move at lower temp?
Or is it because at low temp the...
So the material has a low yield stress at higher temperature, because the disocations are easier to move? When you say thermally activated processes, what do you mean by that?
A brittle fracture fails by rapid crack propagation, as is normally perpendicular to the applied stress...
Thanks for the reply. What is the temperature-dependant mechanism? Ive been looking through a few books and searching google for hours but cant find any difinitive answers. Perhaps my searches arent specific enough.
i found this text though online
I am given the trends for yield stress and fracture toughness as functions of temperature for steel. I need to explain the trends
The Attempt at a Solution
I am guessing the yield stress is the stress that the material can withstand...
