Title: MSAE E4215 Mechanical Behaviour of Structural Materials

MSAE E4215Mechanical Behaviour of Structural
  • Lecturer I. C. Noyan
  • Text Herzberg, 4th Edition-Deformation and
    Fracture Mechanics of Engineering Materials

In this class we will study the response of
engineering materials to applied loads and
displacements under diverse conditions.
We will try to understand why different
materials respond differently to stress and
strain, and how can we modify the mechanical
  • At the end of this class, you will have a basic
    understanding of the processes/parameters that
    govern the mechanical response of engineering
  • You will also be able to do simple variants of
  • Stress and strain calculations in elastic and
    plastic loading regimes.
  • Basic fracture and fatigue lifetime calculations.

Teaching Style
  • I believe in interactive teaching and will ask
    questions during lectures.
  • Your responses will enable me to know you over
    the semester.
  • If you do not know the answer, feel free to say
    I do not know.
  • These questions link the lecture material to the
    real world and may help give you a better
    perspective of what we are doing.
  • This is a survey class each chapter really
    deserves its own course and has its own textbooks
    and monographs. Feel free to read more.
  • I am going to assume that you know ALL the
    material in Callister. Do review it if you need

Exams, grades, etc.
  • Midterm (25)
  • Final (40)
  • Make-up policy Only oral make-up exams will be
    given to those with valid excuses.
  • Term paper presentations (25).
  • Homework Assigned and due weekly-10 Late
    homework loses 25 of points every day.
  • Office Hours by appointment only.
  • Contact info
  • 212-854-8919 (day) /914-238-4832(day)

Term Paper
  • Involves mechanical design, materials selection,
    manufacturing plan and sales price.
  • Must be simple
  • Kitchen knife,
  • Invalid crutch,
  • Baseball bat,
  • Golf ball,
  • Golf club,
  • Glass table, etc.
  • You may work in pairs (2 persons per PAIR)
  • By the end of the second week you must give me a
    project schedule.
  • There will be a full term paper, and for those
    who are at Columbia, a 15 minute presentation.
  • The presentation will aim at raising venture
  • The class will vote on whether it will be funded
    or not.
  • CVN students do not need to do the presentation,
    unless they wish to record a video and send it

Term Paper Basics
  • The term paper should take a simple structure
    from concept to manufacture.
  • You must do the business case, material
    selection, mechanical analysis, fabrication and
    distribution plans.
  • The report contains everything in sufficient
    detail such that it can serve as a starting point
    for a real company copies of powerpoint slides
    will not do.
  • The presentation is just your business case and
    highlights of the technical side. It must include
    net cost and net profit numbers.
