Catalog Description

506 Advanced Mechanics of Materials I. I, SS; 3 cr. Analysis and design of load-carrying members, shear center, unsymmetrical bending, curved beams, beams on elastic foundations, energy methods, theories of failure, thick-walled cylinders, stress concentrations, design to prevent failure by excessive elastic deformation, plastic deformation and fracture. P: EMA 214, 304, or 306/307.

Course Prerequisite(s)

EMA 214, EMA 303, EMA 304, OR ME 306

Prerequisite knowledge and/or skills

This course covers some of the more conceptually difficult subject matter from Mechanics of Materials. A first course in mechanics of materials is warranted before attempting these more advanced topics.

Textbook(s) and/or other required material

Course objectives

Course Objectives: It is the instructor's intention to...

make the student critically aware of the nature of the approximations that are commonly invoked to obtain such "strength of materials" solutions and their likely impact on the reliability and robustness of the resulting design.

enable the student to understand common mechanisms of failures, to analyze potential designs for criticality, and produce designs that can be expected to be reasonably safe from such failures.

Course Outcomes: Students must have the ability to...

understand the usefulness and limitations of formulas derived earlier for practical problems.

perform stress analysis with the aid of calculators, tables and nomographs.

recognize the potential for structural and material failure and apply state-of-the-art theories of failiure.

combine strengths of materials analysis with failure theories to design to criticality.

communicate effectively via written reports.

Topics covered

Stress-strain-temperature relations, stress at a point
Theories of failure and fracture
Plane elasticity
Unsymmetrical bending of straight beams
Shear center for thin-walled beam cross-sections
Bending of curved beams and rings
Energy methods for deflections and static indeterminacy
Thick-walled cylinders
Torsion of non-circular cross-sections
Stress concentration and contact stress
Review and problem sessions
Tests

Class/laboratory schedule

EMA 506 meets three times per week for traditional 50-minute lectures

Contribution of course to meeting the professional component

This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.

The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

EMA 506 follows EMA 303 or 304 in that there is frequently an assignment that requires students to design a structure that satisfies a specified failure criterion. As such, there is an implicit emphasis on health and safety.

Relationship of course to undergraduate degree program objectives and outcomes

This course primarily serves students in the department. The information below describes how the course contributes to the undergraduate program objectives.

EMA 506 is focused to satisfy the EMA educational objectives. It provides an advanced treatment of Mechanics of Materials, a subject involving problem-solving and design-driven project analysis, crucial to those planning a career in mechanics and astronautics. Design-oriented problems are woven into the course, and students are required to prepare professional, written reports of their results. An integrative team design project is carried out.

Assessment of student progress toward course objectives

Two one-hour tests
A two-hour final exam
A design project, simulating the commercial design process and incorporating realistic reporting requirements.
Home work assignments.
