Duration : 2-days

A two-day course aimed at all engineering disciplines, for users who are familiar with linear static structural analysis in LUSAS. The course covers the theoretical and practical considerations of linear dynamic analysis and consists equally of presentations and ‘hands-on’ sessions.

Day 1: Eigenvalue Extraction Analysis

The starting point of all dynamic analyses is a natural frequency analysis. Interactive Modal Dynamics (DYN-2). Vibrational analyses may be performed as a post-processing exercise following a natural frequency analysis. This covers both frequency and time-domain analyses.

  • Eigenvalue extraction
  • Subspace iteration
  • Guyan reduction
  • Inverse iteration with shifting
  • Lanczos eigen-extractions
  • Nonlinear eigenvalue techniques
  • Assumptions, calculations and general procedures
  • Modal excitation and modal damping
  • Calculating results
  • Power spectrum and seismic response

Day 2: Analytical Modal Dynamics

More complex modal analyses may be carried out ‘off-line’ so-to-speak, in LUSAS. This is discussed along with issues arising from damping in the structure. Modal Synthesis & Transient Dynamics. Looks at ways of dividing the structure into component parts, or superelements as they are more commonly known, and carrying out dynamic analyses on the components rather than the whole. Additionally, time-stepping techniques are explored for problems with time-dependent loads.

  • Damping
  • Spectral response analysis
  • Harmonic response analysis
  • Modal synthesis
  • Transient dynamic analysis
  • Implicit and explicit methods
  • Dynamic analysis control
