Learning outcomes
The course is an introduction to computational mechanics of solids and structures. The goal of the course is to provide the students with the fundamental concepts and operating tools to solve current structural problems.
Course contents
The direct stiffness method. Linear elastic rods and beams (Eulero-Bernoulli and Timoshenko beam theories). Truss and frame structures. Specific topics: restraints, constraints, offsets, semi-rigid connections and joint flexibility.
The finite element method (assumed displacement finite
elements).
Eulero-Bernoulli and Timoshenko beam elements. Finite elements for
two- and three-dimensional elasticity. Kirchhoff and Mindlin plate
elements. Finite element modelling and performance. Convergence
requirements. Patch test.
Nonlinear analysis of frame structures. Solution methods. Incremental methods and general control. Geometric stiffness and stability analysis of frame structures. Material nonlinearity. Elasto-plasticity. Limit analyses.
Linear and nonlinear dynamic analysis. Modal and transient analyses. Time stepping methods.

During the lectures, some reading assignments will be made from selected papers in the published literature.
Teaching methods
The course content will be entirely covered by the lectures. The course includes some laboratory sessions, which will cover the practical aspects of the lectures. The instructors will tutor the students.
Assessment methods
A final oral examination is planned, based on questions intended to assess the knowledge and understanding of the topics covered by the course. The student should present and discuss the solutions of some homework assignments and a final project.
Teaching tools
The teaching tools are overhead projector, projector and PC.
The course includes some laboratory sessions at the labs of the School of Engineering.
