Lesson Title

1a. Spring Element with Nonlinear Analysis Parameters (large displacement off): Learn how to run a simple linear analysis, interpret the results and understand the difference between linear and nonlinear behavior.

 

1b. Spring Element with Nonlinear Analysis Parameters (large displacements on): Demonstrate the effects of geometric nonlinear analysis and how to interpret the results.

 

1c. Spring Element with Nonlinear Analysis Parameters (Multi-Step Analysis): Demonstrate the effects of geometric nonlinear analysis with incremental loads through multiple subcases and interpret the results with different output options.

 

1d. Spring Element with Nonlinear Analysis Parameters (Restart a Multi-Step Analysis): Use the Restart feature on the previous exercise to introduce an intermediate load case and use data obtained from the first part of previous analysis.

 

1e. Spring Element with Nonlinear Analysis Parameters (filter using restart): Use another feature of Restart to introduce multi step analysis by keeping only the first part of the analysis as a separate result file.

 

2a. Geometric Linear Analysis of a Cantilever Beam: Perform linear analysis on a cantilever beam under four increasing loads, create an accurate deformation plot of the model and a plot of the load factor vs. displacement.

 

2b. Geometric Nonlinear Analysis of a Cantilever Beam: Perform nonlinear analysis on a cantilever beam under four increasing loads, create an accurate deformation plot of the model and a plot of the load factor vs. displacement.

 

3. Load Deflection of a 3-Rod Structure: Perform nonlinear analysis with the use of arc length increments, create an animation of the deformation of the structure and create an XY Plot of the load factor vs. displacement.

 

4a. Linear Buckling Load Analysis (without spring): Demonstrate the use of linear buckling analysis.

 

4b. Linear Buckling Load Analysis (with spring): Demonstrate the use of nonlinear static analysis restarted with buckling parameters.

 

4c. Nonlinear Snap-ThroughBuckling Load Analysis (different spring constants): Demonstrate the use of nonlinear static analysis for a snap-through load and show the effects of different spring constants on the load-deflection curve.

 

5. Large-Scale Deformation of a Hyperelastic Material: Demonstrate the use of hyperelastic material properties and create an accurate deformation plot of the model.
