Course Summary:
 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.
Who should attend:
LUSAS users familiar with linear static analysis, with a requirement for
dynamics.

courses.
Some delegate
feedback from recent LUSAS training courses:
-
“This
class was excellent and one of the best training courses that I
have taken." (Tim E.)
-
“Very
good demonstrations/teachers with a good variety of hands on
examples.” (Douglas R.)
-
"The
instructor was phenomenal! Engaged, energetic, helpful and
friendly! Could not have asked for a better one." (Joe K.)
Course Details:
Day 1:
Eigenvalue Extraction Analysis (DYN-1)
The starting point of all dynamic analyses is a natural frequency
analysis.
- Eigenvalue extraction
- Subspace iteration
- Guyan reduction
- Inverse iteration with shifting
- Lanczos eigen-extractions
- Nonlinear eigenvalue techniques
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.
- Assumptions, calculations and general procedures
- Modal excitation and modal damping
- Calculating results
- Power spectrum and seismic response
Day 2:
Analytical Modal Dynamics (DYN-3)
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.
- Damping
- Spectral response analysis
- Harmonic response analysis
Modal Synthesis & Transient Dynamics (DYN-4)
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.
- Modal synthesis
- Transient dynamic analysis
- Implicit and explicit methods
- Dynamic analysis control
