    ANSYS Discovery Live - how does it work? (in general)

    Hi All, ANSYS just issued new software, please see Link. (I am not reseller, I am not working for ANSYS). As one may see looking at the marketing video, the new idea in ANSYS is to be able to modify model geometry on run and see stress results plots change in the same time. I am wondering how...

    Best software for 3D shell/plate geometry modelling (for FEA purposes)

    Hi All! I would like to ask you, what is your favourite software and why, which you are using for creation of various shells and plates geometry in 3D space (which is next being exported to FEA software)? I am looking for your recommendation as well as few words about the feature available at...

    Blast Design in FEA - what acceptance criteria

    Hi All, My question is in regards to blast design in FEA, e.g. using ANSYS Explicit Module. I will create steel structural system consisting of shell/plate elements only, this means any girders will be simulated by few shells. Loading will be transient with peak value simulating the blast...

    ASCE Blast Design - what acceptance criteria?

    Hi All, My question is in relation to ASCE Design of Blast Resistant Buildings in Petrochemical Facilities document. Analysis of mine will be performed with Finite Elements in ANSYS Explicit Module, all structural system modelled by shell elements (e.g. girder will be simulated by few...

    Explicit Analysis vs Transient Structural Analysis

    Hi All, ANSYS documentation gives a recommendation that for the events duration below 1sec (blasts, shocks, etc.), Explicit Analysis is recommended, while for longer times, Transient Structural Analysis is appropriate. May I ask you, why is it so, and how do you choose whether or not which of...

    Recommendation on literature/documents to start with Composite FEA

    Hi All, Please give your best recommendation on materials (literature, presentations, online pdfs, etc.) to begin with Composite FEA, e.g. FRP design/damage and acceptance criteria, fibre reinforced thermoset composites. Preferably for marine industry, but other experiences are also welcomed...

    Solid Finite Element vs Through-thickness stress close to yield point

    Hi gents! I would like to ask you about your engineering opinion on following FEA case. Given is thick plate (40mm thickness) with dimensions in plan of 500x500mm. It is modelled by solid finite elements with edge of 10mm each. At some small area of this plate, in effect of loading conditions...

    Frequency Response and Transient Stress

    Hi All, Today my questions consider linear dynamics. Please see them below. 1.Could you please tell me should one expect results from Frequency Response to be somehow corresponding with results from Transient Stress analysis? 2. If yes, please let me know the relationship. 3. What output/result...

    Buckling Factor without imperfection < Buckling Factor with imperfection (?!)

    Hi gents, As per figure below, I have performed simple test for beam in Critical Buckling Load linear analysis. First model is beam without any imperfection introduced. Buckling Load Multiplier (BLM) is 65. Second model is based on scaled unitless deformation from the first model, hence...

    DNV - E273, Padeye Design, Dch definition missing

    Hi Gents, Could you please help me, question is about DNV-ST-E273 2016, Appendix A, Padeye Design. At A5 we have weld check for cheek plates, in the formula there is Dch value. There is definition missing in the code. One may try to use padeye hole diameter, but for me it would rather be 2*Rch...

    Java - IDE NetBeans - Upgrading excel-like spreadhseet to the windows-like desktop application

    Hello All, I am dosing my best, learning Java as a very beginner and my very first purpose is to produce small GUI desktop app for quick engineering calculation. For GUI app I already found IDE NetBeans will be efficient for me. My question is simple (please excuse me this, still at the...

    Result Calibration Singularity

    Hi folks, This time I would like to ask about your opinion. Below figure is self-explaining, you may notice 150 MPa applied to the tip of smaller solid object (lets assume it is mild steel) and below, larger box is providing supports. Assuming it is converged enough, in this simple example it...

    Pipe Effective Axial Force from the fluid inside the Pipe - how to include in solid FEA?

    Greetings. My question is in reference to the Effective Axial Force phenomena. Please imagine pipeline constrained at the ends and loaded with internal pressure, with fluid inside. From structural perspective, internal pressure, constraints and Poisson's ratio will effect in Tensile force in...

    DNV - Yield Check Allowable Values - How to include plate bending stress?

    Greetings Folks, Important question. I am using general FEA software, now I have started work with DNV, and I am using DNV-OS-C201 with (page 41) yield check usin von Mises stress for plate finite elements in my model, but DNV states allowable stress for membrane stresses only, there is guide...

    General FEA software and extraction of bar internal forces to external spreadsheet

    Hi Gents, The problem I would like to adress to you all, is to ask you for advise in creation of Excel spreadsheet which will be used to perform code check on beam elements. Values of internal forces will be extracted from general FEA software and imported via csv file to the mentioned Excel...

    Weld strength calculation according to ABS

    Greetings, Could you pleae advise, in which particular code of ABS one may find strength calculation formulas for stresses in welds ? (Not minimum dimensions scantlings, I am asking about detailes design procedure and allowable stresses).
