Hi, 

 

Is the plastic strains plots in hyperview is the %plastic strain or just a number.

If the maximum plastic strain is say 0.023, does it mean the plastic strain as 0.023%. if it is not how do I convert to percentage value?

    Hi Kamalakar Rao,

     

    Strain is a ratio of Change in length/original length. The same times 100 gives the percentage.

     

    The result depends on your input. If your input is in %, the result output will be %

    you can do pretty much anything in the legend options in HV.

    You can multiply your solver result by a scale factor (100) and in the 'Edit Legend' you can change title, and much more of your legend.

    by the way, in OptiStruct you need to request STRAIN(H3D) under GLOBAL_OUTPUT_REQUEST.

     

    And them you will see Strains in the result file. P1 Major would be the Maximum Principal Strains.
