Background to transient analysis
- [Instructor] This video looks at the background to transient analysis. In transient analysis we calculate the response to a time-varying input. Input excitation is always defined in the time domain. Now the excitation type can be via applied forces or enforced motions such as displacement, velocity, or acceleration. The excitation can be via an external input like a hit or a strike, or a base motion input like a shake or a shock. The excitation can be applied for the whole duration of the analysis or for just part of the time. We'll look at an example the plate model where we applied an impulse load; the shape of the impulse load and the corresponding table to define it is shown here. The duration of the impulse is 10 milliseconds. Putting a lead-in or a zero input for a millisecond or so like this can be very helpful to many solvers. I have also extended the tail out to 20 milliseconds; in other words I've got a flat line. That ensures that any extrapolation will always happen…
