Educational Goals

Upon successful completion of the course, students will be able to:
1. understand the basic principles of the plastic behavior of truss structures
2. formulate and solve an elastoplastic loading problem of a medium and calculate stresses and
strains
3. select a yield criterion depending on the structural material,
4. analyze collapse mechanisms in truss structures
5. determine manually or using computational tools the collapse load of frames

Students Evaluation

1. Assignment of tasks aimed at exploring the understanding
of the concepts taught.
2. Final written exam at the end of the semester (in Greek).
3. Each student is given the opportunity to review their
written exam and have their mistakes analyzed.
