LS-DYNA Analysis Models
Here we are showing a collection of sample models created through LS-DYNA by Lancemore FEA team. LS-DYNA is useful not only for the nonlinear structural analysis, but also for analyzing FSI (Fluid Structural Interaction) and supporting the implicit method function. It also covers a wide range of fields including particle method, vibration and acoustic analysis, and we are expecting that the range will keep on expanding in the future.

The sample models have been created and collected below for the purposes of letting you know what LS-DYNA can do and demonstrating our knowledge and abilities to create models. We are hoping that our models come in useful for you. If you wish to create a particular model, please contact us. We will offer the best cost-effective solutions. Thank you for your interest in our models!

Buckling of a Submarine Pressure Hull
Problem: A submarine pressure hull is modeled by plate and bar elements. Using MSC SimXpert, check the pressure hull for buckling at an operating depth of 1000 ft which is equivalent to an external pressure of 445 psi.

Step 4- Apply Boundary Condition

...
Step 9 - Plot Mode Shapes - Second Mode Deformation Plot.
7) Note the Buckling Load Factor.
