With this function you can construct your weekly calendar of lessons, which is customized on the basis of the courses that you intend to follow. Warning: the personal schedule does not replace the presentation of the study plan! It's an informal tool that can help you better manage the organization of class attendance before the study plan presentation. After the study plan presentation we recommend you to use the Lecture timetable service in your Online Services.
To create your customized schedule follow these instructions:
- Click on the "Enable" link to proceed. You will be asked your surname and first name in order to determine your alphabetic grouping.
-
To add or remove courses from your personal schedule, use the small icons which are found next to the courses:
addition of the course
removal of the course
selection of the section of the Laboratory of Architecture (Note: the effective area in which the teaching will be carried out will be determined after the presentation of the Study Plans)
-
The sidebar on the left displays the number of lessons included in schedule.
There are also these commands:
View the schedule: allows the viewing of the weekly synoptic schedule
Delete the schedule: cancels the selections made
When you have finished the entry, you can print the calendar you have made.

Course Description

- VISCOELASTIC BEHAVIOUR OF POLYMERS
Constitutive relations and their role in engineering problems. Recall of basic concepts and definitions in solid and fluid mechanics.
Rheological constitutive equations for polymers. Non-Newtonian shear behaviour of polymeric fluids. Example: analysis of the flow in a pipe.
Shear viscosity-to-structure relationships in polymers. Shear viscosity dependence on temperature and pressure.
Behaviour of polymers under 'simple' histories of the mechanical stimulus. Energetical consequences of the viscoelastic behaviour. The theory of linear viscoelasticity. Boltzmann's superposition postulate. Analogue models. Convolution integral and constitutive equations. Laplace transforms. Interconversion between transient properties. Interconversion between transient and steady-state properties.
General temperature dependence of viscoelasticity. Linear theory of thermo-viscoelasticity: time-temperature 'equivalence'. Master curves and shift factor. Arrhenius' and Williams-Landel-Ferry's shift factors. Thermo-mechanical Spectrometry (time/rate/frequency or temperature scans)
Problems
- POLYMERS AND COMPOSITES FAILURE AND DURABILITY
Environmental effects and degradation mechanisms. Reversible and non-reversible mechanisms. Chemical and physical ageing. Ageing control strategies.
Shear yielding and crazing mechanisms. Yield criteria. Time and temperature dependence.
Introduction to fracture mechanics. Strain energy release rate and stress intensity factor. The correspondence principle for viscoelastic materials. Application of the correspondence principle to fracture initiation and fracture propagation in polymers. Failure in composite materials.
Case histories: durability of dam membranes, failure of pressurised polymeric pipes by slow crack growth, composite repair systems for damaged pipelines.
