    Adaptive Remeshing in LS-DYNA

    I am trying to run some axi-symmetrical plasticity simulations and want to add adaptive remeshing in order to prevent the axi-symmetrical elements from turning inside-out during the simulation. I have flagged my parts for adaptive remeshing under the *PART card, but my problems occur in...

    Rivet countersinking by dimpling

    Thanks Russ, your input is useful. I am interested in some of the manufacturing mwethods you used in producing dimples. If I am correct, 0.040 inch 2024-T3 is thin enough to be cold dimpled. I am curious though whether coin or radius dimpling is typically used. Also, are the dimples...

    Rivet countersinking by dimpling

    I am looking for information on dimpling as a countersinking method in aircraft panels. I have found a lot of information on techniques used for home-built aircraft, but I am more interested in dimpling of thicker sheet materials. Specifically I am looking for information on sheet thickness...

    Placing "Given" solve blocks into loops

    I am aware of the vectorize operator, and that could solve my problem. The problem is I am using a database of formulas programed into mathcad which were not set up to hgandel vectors in the first place. I could edit all of the equations, however since this database containes over 150 pages of...

    Placing "Given" solve blocks into loops

    I was wondering if there was a way to place a Given sove block within a while loop or for loop. For instance, I would like to solve: For x = 1-9 Given f(x,a) = h(x,a) Find(a) Typically, I would just enter in x as a vector of numbers, however the system of equations I want to solve for is...

    Indefinite Integrals

    I was wondering if there is a way of evaluating indefinite integrals with conditions on the integral which define the constant of integration. For instance, I would like to be able to input a function, f(x) = x, and the boundary condition F(2) = 4, and receive F(x) = 0.5(x)^2 + 2. Thanks for...
