SOLID MECHANICS 2 - 2021/2

Module Overview

The module provides students with further insight into the response of structures to static load, to include elastic deformation and plastic collapse. In addition students will receive an introduction to vibrations by considering simple 1o freedom systems and a more in-depth understanding of the mechanics underlying modern composite materials.

Stiffness and strength of UD laminates,

Mechanics of composite laminates containing plies of varying orientations,

Assessment pattern

Alternative Assessment

Alternative assessments for class tests will be coursework assignments.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their abilities (i) to apply the principles of mechanics to cases of axial load and bending and to calculate forces and displacements in statically determinate beams and/or trusses, (ii) to apply the principles of simple dynamic systems to the solution of vibration/oscillatory problems and (iii) to analyse the mechanical behaviour of unidirectional and multi-ply composite laminates.

Thus, the summative assessment for this module consists of:

• Examination (2 hours) [Learning Outcomes: 1-8] {80%}

The coursework comprises 3 elements as below:

• Mechanics Quizzes                                               [Learning Outcome: 1] {10%}


• Class Test in Dynamics                      (40 minutes) [Learning Outcome: 4] {10%}

Formative assessment and feedback

Formative assessment and feedback is provided via the weekly supported tutorial work  (15 hours) and through self-assessment exercises provided via SurreyLearn.  The students complete a set of worked solutions to a range of questions in the tutorial classes and are provided with tutor support in comment and feedback in the sessions.  Students also receive written feedback on the class tests.

Module aims

• To introduce the students to the deformability of structures and the principles of the elastic analysis of statically determinate structural forms. Also students will learn how slender structures under in-plane compressive loads collapse.
• To develop an understanding of the dynamic response of un-damped and damped single degree of freedom systems under free and forced vibration.
• To explore further the mechanics of composites materials, a topic introduced in a 1st year module (ENG1063).

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce solid mechanics principles in the areas of stress analysis, dynamics and mechanics of materials through theory with worked examples.  This is delivered principally through lectures and tutorial classes.

The learning and teaching methods include:

• Mechanics lectures (11 hours) and tutorials (5 hours)


• Dynamics lectures (11 hours) and tutorials (5 hours)


• Composite Mechanics lectures (11 hours) and tutorials (5 hours)


• Revision lectures (3 hours)

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
