PERIODO: MAGGIO

The aim of this course is to introduce concepts and calculation methods for responses of linear viscoelastic materials. The approach will be presented using principally a strength of materials approach, but with linkages to general continuum mechanics methods at the end of the course.

This course will have the following objectives;
• Derive a mathematical model for linear viscoelasticity from a mechanical analog and apply the theory to experimental data in order to characterize the parameters of the associated models;
• Apply Laplace and inverse Laplace Transforms to relate elastic solutions to viscoelastic problems;
• Calculate the time-dependent stress (strain) response to a generalized strain (stress) input; and
• Derive the time-dependent linear viscoelastic response functions from the frequency-dependent response functions and vice-versa.
