    effect of water acceleration in transient dynamic analysis

    Dear all, I would to like to perform transient dynamic analysis of structure in ANSYS ,where internal static pressure has been applied . I have a query regarding how to consider the dynamic acceleration of inside water in analysis.I am using SHELL181 element for analysis. Any input or help in...

    Response spectrum analysis

    Dear all, I am interested in carrying out transient analysis of structure where I have load on model as a "acceleration time history" from shock standard. I have a question that in such case I have to do analysis as a normal transient analysis or any response spectrum analysis is needed for...

    Time vs acceleration input

    Dear all, I am using ANSYS 15.0 mechanical. I have a query that is it possible in ANSYS to input “time Vs acceleration” history as an input? I know that pressure, displacement time history can be given as input using “Existing table” option in ANSYS , similarly can I use ACEL command ? .ANSYS...

    Stress concentration near the boundary condition

    Dear all, I am working on Solid model in ANSYS which is propeller. I have solved the model with fixed boundary condition at the bottom. The stress contour of same model shows the stress concentration near to boundary condition. The reason for that is the sudden geometric variation in the model...

    whipping analysis

    DEAR ALL, I am doing whipping analysis in ANSYS. in order to carry out analysis I have pressures calculated from CFD at each time interval .(i.e. from Star ccm software) .My aim is to calculate the vertical bending moment (VBM) amidships, from literature survey I understood that I have to remove...

    Damping for selected mode in ANSYS

    Dear all, I am doing mode superposition analysis in ANSYS mechanical, where I am interested in modal analysis in one of its steps. In Ansys is it possible to apply damping ratio for particular modes? i.e different damping ratios for different modes. e.g. I have obtained the modal analysis in...

    Stress from FEA analysis of propeller

    Dear All, I am working on project called "strength analysis of highly skewed propeller", where I have to find maximum and minimum stress on propeller blade from structral analysis in ANSYS. The load condition considered in the analysis is Free sailing ahead condition . I am confused with stress...

    segmention in ship model testing

    Dear all, I have an doubt regarding ship model testing , It is observed that the ship model testing for slamming, whipping phenonmeneon is carried out for "Segmented" model.I am working on Whippping analysis problem and came across different papers which is showing segmented model. Does anyone...

    about use of Goodman fatigue diagram

    Hi friends, I am working on propeller analysis, where I have to calculate safety factor for NiAl bronze material in order to check its strength. After reading various materials on it, I understand that Haigh diagram (Goodman line) is generally used for it. I have referred same diagram for NiAl...
