    LINK 180 ELEMENT PROBLEM

    Dear friends of the ANSYS forum, I am new on the use of ANSYS, and for instance I am performing basic tutorials such as the next: https://www.youtube.com/watch?v=T9V6lZSyjcs But I have a problem from starting :-(: I have tried to do the next tutorial, but when I try to define the section...

    LRFD coefficients for load combinations

    Dear friends, Thank you very much for your response. WannabeSE, you are right so on that date it was not possible to use LRFD... so it was not incorporated on code yet. And Lomarandil, you said what I refer: the structure is on good state, it has some elements that by visual testing show...

    LRFD coefficients for load combinations

    Dear friends from eng-tips, I am performing the analysis of a steel construction of 50 years old. What I know the LRFD coefficients are based on this period of time. I have the next question: if I want to study the structure with new loads from equipements, and the new period of time is 30...

    MODELATION OF SOIL PRESSURE ON MODAL SPECTRUM ANALYSIS

    Dear friends, As I comment on the subject,I am evaluatin the structural performance of a steel structure sopported on walls. Due to the complexity of the design, I am using the modal spectral analysis to evaluate the seismic actions. But my question is the next: How can I consider on this type...

    ANSYS APDL-Beam orientation

    Dear friends, I have a problem that I want to solve in ANSYS Mechanical APDL. On a beam section, I want to change the orientation of the local system of the beam. Could you please tell to me how I can do that in ANSYS. Thank you very much. Regards, 3JC

    Need to learn NX Nastran

    Dear Tejras, In complex models such as you comment, usually is simulated an equivalent model. What I recomend to you is start with something basic (for example the chassis), and making simplifications. Everything this depends on what do you want to analyze. I recomend to you to read and study...

    Standar or references for semi-trailer load capacity calculation

    Dear Greg: Thank you very much for your response. But the problem is that in the country where I am emplaced, in Bolivia, there is no so much information about everything that you say, and costs are prohibitive. For these reasons I want to start the study by analyzing the structure with finite...

    Standar or references for semi-trailer load capacity calculation

    Dear GregLocock: Thank you very much for your response. I don't know then if exists any specification about tests to perform on this type of structure for the homologation of the support. It will be vaid to try to reproduce them on finite element analysis. Thank you. Regards, 3JC

    Alternatives to Abaqus to open inp and odb archives

    Dear friend, Thank you very much for your response. What I know is that Hypermesh can generate and open different formats of FEA sotwares. Is there any free alternative with similar characteristics, for ABAQUS mainly? Thank you very much. Regards, 3JC

    Alternatives to Abaqus to open inp and odb archives

    Dear collages, I want to know about any free alternative to open inp and odb archives developed by Abaqus. I've got a client who want to visualizate the models that I perform. Thank you very much. Regards, 3JC

    Standar or references for semi-trailer load capacity calculation

    Dear collages, Hello to everybody, this is the first post that I do in this section. I am a FEM analysit, and I have to develop the structural analysis of a semi-trailer. Which specification shall I have to use for the determination of load cases and the matnitud of that loads and/or impossed...

    Visualization of wires

    Dear corus, Thank you very much, the problem is resolved yet. I don't know why, but the configuration of the model broke down and there were not any section assigned to the wire. Thank you very much anyway. Regards, Juan José

    Visualization of wires

    Dear Corus, Thank you very much for your answer, but I have tried to do what you say and I haven't got any results. Is it necessary to do anything else? Regards, 3JC

    Visualization of wires

    Dear collages of the forum, I've got a question that I can't find how to resolve. What I want to do is to make a 3d representation of a wire section (on other software packages, such as SAP2000, is named as ). I want to represent on the Assembly module the wire like a 3d part. Is this possible...

    How to model beam on elastic foundation in ABAQUS?

    Dear oesa: It is possible to define spring in each node (divide the beam into a number of nodes previously). The problem is if you have tensiones (uplifts). I think sap2000 is easier to perform this analysis. Regards, 3JC

    Deflection of beam in plastic range according to moment-curavutre properties of the section.

    Dear wannabeSE, Thank you very much for the link. The propose of the study is for research (PhD), and therefore is more theoric. Regards, jJ

    Deflection of beam in plastic range according to moment-curavutre properties of the section.

    Dear briancpotter, Thank you very much. Just I was cheking this text, and is very good on the topic (and also covers things that another not). Regards, jJ

    Deflection of beam in plastic range according to moment-curavutre properties of the section.

    Dear BAretired, Thank you for your response. On my particular case I have a multilinear stress-strain relationship for steel (linear, yielding, hardening and post-critic). Once I have obtained the moment-curvature for rectangular cross section (I have yet performed this task), could you...

    Deflection of beam in plastic range according to moment-curavutre properties of the section.

    Dear rb1957, On construction applications, connections are calculated usually by the plastic resistance. You can see more information about this in the next link that I send in attach. In mechanical and aerospace engineering the problem is usually the high cycle fatigue; in structures submited...
