NMT Course Syllabus 3 COURSE DESRCIPTION The Advanced Strength of Materials Course will focus on advanced strength of materials principles and techniques for use in mechanical engineering design and problem solving. Mechanical engineering designs are increasingly complex and require a range of mechanics skills including, predicting material failure under steady and cyclic loading, determining the stresses and deflections due to unsymmetrical loading, understanding nonlinear structural deflections and resulting residual stresses, computing shear stresses in thin-walled structures, analyzing for stresses in axisymmetric thin-walled shells and thick cylinders and predicting the stability of elastic beams and shells. All of these important mechanics skills must be utilized by a mechanical engineer to make informed design decisions and to solve many engineering problems. This course will be taught in nine major modules, representing important advanced strength of materials skills a mechanical engineer should master. Homework problems will be assigned for analysis and class discussion. The homework problems will use examples that will assist in understanding the principles involved and their application.

COURSE OBJECTIVES The course is designed with the following objectives in mind: 1. Students should gain a thorough overview of the advanced strength of materials skills required for today's mechanical engineers. 2. Students should obtain an understanding of advanced strength of materials principles and practices that should assist them in making informed design decisions and solving complex problems. 3. Students should develop the framework for understanding how advanced strength of materials complements other mechanics technologies used in engineering organizations.

GENERAL OUTLINE The following major topics will be covered by the course. Copies of notes for each lecture will be posted on the WebCT class page. This will be done prior to the lecture so that students can make hard copies for taking notes during class. Reading will be assigned on each topic from the formal text. It is expected that the reading will be done on a subject after it is covered in the classroom lecture. Exercises from the text will be assigned as homework at the end of each class. This should be completed and submitted to the instructor prior to the next class. Students will be expected to be prepared to discuss their analysis of the exercises during the class. The class will discuss the results and provide additional recommendations or on the analysis. Introduction (1 session) Topics covered include potential applications of strength of materials, methods of analysis and a review of some first principles in strength of materials.

NMT Course Syllabus 4 Stress-Strain and Material Behavior(3 sessions) Topics include principle stresses and strains, stress-strain relationships, material yielding, elastic-plastic behavior, stress fields in nonlinear bending, and residual stresses. Torsion (1 session) Topics include torsion in circular and rectangular cross sections, torsion in thin-wall sections and design considerations for torsion. Unsymmetrical Bending (4 sessions) Topics include bending of beams with arbitrary cross sections, beam displacements, beams with thin sections, shear centers, curved beams and beams on elastic foundations. Thick Walled Cylinders and Disks (1 session) Topics include stresses and displacements in thick walled cylinders, centrifugal stresses in disks, shrink fits, membrane stresses in thin cylinders and spheres, and strains and displacements in thin walled shells. Elastic Stability (1 session) Topics include buckling and stability of columns. Local Stresses and Material Failure Behavior (3 sessions) Topics include stress concentration factors and material failure under static and cyclic loading. COURSE DELIVERABLES Homework problems - Students will be assigned textbook reading and exercises as part of a weekly homework assignment. Students should be prepared to discuss their findings using the discussion link of WebCT and during the next class. Quizzes - A short quiz will be conducted via WebCT during the week following a lecture. The quiz will emphasize major themes of the prior week's lecture and will assist the instructor in ing that key course material is being adequately conveyed. Interim Exam - An interim exams will be conducted for the class. It will emphasize the major content of the course sessions to that point and will indicate the student's assimilation of the course material covered. Final Exam - A final exam will be conducted for the class. It will emphasize the entire contents of the course and will indicate the student's assimilation of the entire course material covered. COURSE GRADING The course grade will be computed from the following components: 1. Homework Problems 2. Quizzes 3. Interim Exam 4. Final Exam

ACADEMIC HONESTY Academic honesty is highly valued at New Mexico Tech. A student must always submit work that represents his or her original words or ideas. If any words or ideas are used that do not represent the student's original words or ideas, the student must cite all relevant sources. The student should also make clear the extent to which such sources were used. Words or ideas that require citations include, but are not limited to, all hardcopy or electronic publications, whether copyrighted or not, and all verbal or visual communication when the content of such communication clearly originates from an identifiable source. Academic dishonesty could involve: 1. Having a tutor or friend complete a portion of your assignments, 2. Reusing assignments from other classes in this course, 3. Having a reviewer make extensive revisions to an assignment

Grasps subject matter at a level considered to be good to very good. Is an active listener and participant in the workshop discussions. Writes well. Accomplishes more than the minimum requirements. Work in and out of the workshop is of high quality. Example: "B" work indicates a high quality performance and is given in recognition for solid work; a "B: should be considered a high grade. Demonstrates a satisfactory comprehension of the subject matter. Accomplishes the minimum requirements, and displays little or no initiative. Communicates orally and in writing at an acceptable level for a college student. Has a generally acceptable understanding of all basic concepts. Example: "C" work represents average work. A student receiving a "C" has met the requirements, including deadlines, of the course. Quality and quantity of work in and out of the workshop is below average and barely acceptable. Example: "D" work is ing by a narrow margin.

Quality and quantity of work in and out of the workshop is unacceptable. Example: "F" work does not qualify the student to progress to a more advanced level of course work.
