## How to create Contacts with a BCTABLE Card by NASTRAN SOL101

For contact simulation between two structural components with MSC Nastran is necessary to perform a static analysis (Linear Simulation by SOL101 or Non Linear Simulation by SOL106) using CGAP elements with possible convergence problems. This type of modeling is complex because … Continue reading

## Contact simulation with MSC/Nastran

Linear Gap The linear GAP is the simpliest contact form used in Nastran simulations. Linear GAP can solve a large class of problems like hole bearing, heel-toe interaction, fitting contacts. Linear, therefore does not include frition, large displacements, and … Continue reading

## Non linear Buckling with FEM approach

Buckling analysis assesses the stability characteristics of a structure. An accurate solution to a buckling problem requires more efforts than just following a numerical procedure, there are a number of factors to consider before a buckling solution can be accepted … Continue reading

## Non Linear Analysis SOL 106

In the most of cases the nonlinear effects in structures occur due to nonlinear material behavior and large deformations. Geometric nonlinearity becomes relevant when the structure is subjected to large displacement and rotation. Geometric nonlinearity effects are prominent in … Continue reading
