Geometric nonlinearity

• large deformations
• large rotations
• beam structures with buckling, lateral buckling and lateral torsional buckling
• Evaluation of cables and suspension structures
• Determination of stiffening effects
• Buckling of shells
• automatic load determination
• failure due to loss of bar strength

The option RTnlgeo is able to calculate both bar constructions and plane structures in a geometrically non-linear way. This, together with the clear control of the non-linear calculation, results in the following advantages:

• Realistic analysis of the actual structural behaviour
• Acquisition of stability failure concerning buckling, flexural-torsional buckling and bulging
• Acquisition of failed bars
• Consideration of stiffening effects for a more economic component design
