## ME20016: Solid mechanics 3

Owning Department/School: Department of Mechanical Engineering
Credits: 6
Level: Intermediate (FHEQ level 5)
Period: Semester 1
Assessment: CW 15%, EX 85%
Supplementary Assessment: ME20016 Re-Assessment Examination (where allowed by programme regulations)
Requisites: This unit is not normally available to visiting/exchange students.
Description: Aims:To introduce the vibrations of mechanical systems in a one degree of freedom context.
To introduce the theory of torsion in non-circular and open- sections, dual axis bending and the concept of fatigue failure.

Learning Outcomes:
After taking this unit the student should be able to:
* Set up the equations of motion for systems with one degree of freedom; find natural frequencies of free motion; calculate rates of decay from viscous damping and vice versa; determine motions resulting from a sinusoidal force, unbalance and base excitation.
* Estimate maximum responses using shock spectra.
* Calculate shaft critical speeds.
* Calculate torsional stiffness and strength values for closed and open structural sections.
* Predict bending stresses in dual axis bending.
* Predict the fatigue life of some simple structural forms based on S-N calculations.

Skills:
Problem solving; numeracy; working independently.

Content:
One degree of freedom systems: free and forced vibration; base excited motion; unbalance excitation; vibration isolation. Torsion of open and closed structural sections, dual axis bending. Stress concentration, fatigue strength and cumulative damage in structural components. Solid mechanics laboratory experiment.
