    Stress Concentration Factor Calculation For a Rectangular Hole

    Hi Everyone, I have set up an FEA simulation in ANSYS for the following specimen. The left side of the plate is fixed and two points force applied on the right side of the plate (negative Z direction). I have calculated the bending stress at the location of interest using this formula: How...

    Deflection calculation of a variable cross section cantilever beam

    Hello Everyone, Thank you for your help. Your posts are very useful. I have managed to work out yesterday using the integration method. It turned out there was a typo in my MATLAB code... Rocky mistake, I know... Yes, it is for an assignment. Thanks again guys...

    Deflection calculation of a variable cross section cantilever beam

    Hello Everyone, I am trying to calculate the maximum deflection of a beam that has a variable cross-section. I have tried to follow this method: https://mentoredengineer.com/determining-deflection-in-variable-cross-section-beams/ However, my beam consists of 3 sections. Therefore, I extended...

    Shell Edge Load Application on a Plate

    Can someone give me a scientific reason why the maximum stress is lower when the rigid body constraint is applied on the top edge?

    Analysis Validation By Hand Calculations - Unit Error?

    Thanks for the tip. I have setup a 2D simulation. My results are very close but they are still out by a factor of 10 for some reason

    Analysis Validation By Hand Calculations - Unit Error?

    Hi Everyone, I have modeled a plate with a center hole in Abaqus as a 3D model and used shell elements. In order to stop the top edge from bending during the load, a Pin(nodes) constraint has been applied on the top edge. I have worked in mm when I modeled this component. My dimensions have to...

    Shell Edge Load Application on a Plate

    Thank you for your quick response. I have applied a rigid body constraint on the top edge with "Pin" region type. It seems to work well. :)

    Shell Edge Load Application on a Plate

    Hi Everyone, I have modelled a 3D plate using shell elements in Abaqus. I have applied a fixture to the bottom edge and load on the top edge of the plate. The setup and the result of the analysis: As you can see, the top edge of the plate where the load is applied is curved in the direction...

    Importing experimental data into Abaqus, is it possible?

    I have the XY coordinates and their relevant strain values. Is there an easy way to overlay this dataset on the corresponding surface of the FE model and calculate some sort of error between them in Abaqus without writing a script in Python?

    Importing experimental data into Abaqus, is it possible?

    Hello Everyone, I am working on a project where I need to create a 3D FE model of a 4 point bend test and validate the analysis results using surface strain measurements. I have already created setup the experiment in Abaqus and I have the experiment data. I just need to validate my simulation...

    4 Point Bend on an L Shaped Specimen

    Thank you for help. It works fine now :) I have another question... How can I export the principal stresses which occurs at each node on the top surface of the specimen?

    4 Point Bend on an L Shaped Specimen

    Thank you for your guidance. It is much appreciated. I tried to follow your advice and I couldn't make it work. I used a different approach which seems to give me a better result than I got yesterday. However, the penetration at the lower pins are still present. I tried to assign rigid body...

    4 Point Bend on an L Shaped Specimen

    Thank you for your advice, I followed it. I also moved the top two pins down using a boundary condition instead of the reference point method. It seems to work. Although, there is an interesting phenomenon that I don't understand what's causing it. As you can see on this picture, the bottom pin...

    4 Point Bend on an L Shaped Specimen

    Thanks for the info. I think something is wrong as I don't see any forces or displacement on my plots. https://files.engineering.com/getfile.aspx?folder=e0b17a9e-25b4-4b2b-a31a-c16fcb992fe3&file=Capture.PNG...

    4 Point Bend on an L Shaped Specimen

    Hi Everyone, My final year project involves modeling a 4 point bending on an L shaped specimen (only elastic). I am new to Abaqus, I have only used Solidworks simulation before. I am using Abaqus 6.14. I used the instructions provided in this video to set up my FE model...
