## ING2308 Statics and Mechanics of Materials

The course will provide good knowledge of statics and mechanics of materials, which can also be applied in other technical specialisation courses later. The cadets will be given the education necessary to handle operating and maintenance issues within naval and marine engineering. The course will provide a good basis for further studies.

The course covers the following academic content: forces and couples (resultant force, resultant of parallel forces), coplanar systems of forces and two-dimensional structures (concurrent forces, moment of force, resultant force and equations of equilibrium, forces of reaction, connections, statically determinate and indeterminate structures, distributed forces, friction forces, composite structures, trusses, frames, cables and ropes, anchoring), three-dimensional force systems (concurrent forces, couple vector, moment of force as a vector, moment about an axis, resultant and equations of equilibrium, centre of gravity, centroid of area, centroid of volume and centroid of curve), internal forces (shear force, bending moment, shear and moment diagrams for beams, differential relations between load, shear, and moment), mechanics of materials (normal stress, shear stress, strain, elastic behaviour and fracture, temperature effects, normal strain, shear strain, volumetric strain, strain components, principal strains, stress components, principal stresses), Mohr’s circle, elastic materials, generalised Hooke's law, design criteria, Tresca and Mises yield criteria, Coulomb's theory of torsion for cylindrical rods, shafts, bending stress in beams, flexure formula, moment of inertia of an area, longitudinal shear force, transverse shear stress, beam deformation, differential equation of the elastic curve, the unit load method, beams with unsymmetrical cross-sections, composite beams).

The course follows STCW code tables A-III/1 and A-III/2 and the STCW function marine engineering at the management level.

The course will be provided by a civilian higher education institution.

Knowledge

After completing the course, the cadet is able to:

- describe key concepts and methods in statics and mechanics of materials

Skills

After completing the course, the cadet is able to:

- reason systematically when solving statics and mechanics of materials problems and explain the results
- use acquired knowledge to create mathematical models of selected problems within the theory of statics and mechanics of materials, and make calculations related to equilibrium, stability, deformation and strength of materials
- set up equations of equilibrium for determinate and simple indeterminate systems in two and three dimensions and calculate related stresses and deformations
- make force calculations in connection with anchoring and mooring
- examine bulkheads/hatches in a maritime accident

General competences

After completing the course, the cadet is able to:

- use a scientific approach and scientific methods to problem solving
- analyse force systems, equilibrium and stability in two and three dimensions
- evaluate the mechanical properties of materials
- formulate and solve practical problems related to equilibrium, stability and deformation

Examination is carried out according to the Regulations for Admission, Studies and Examinations (in Norwegian, “Forskrift om opptak, studier og eksamen”) at the Norwegian Defence University College.
