PREREQUISITES:
Knowledge of linear elasticity theory is required to take the class.
INSTRUCTOR:
COURSE DESCRIPTION:
Introduction to linear viscoelasticity; methods of characterizing viscoelastic material behavior;
analytical and approximate solution techniques for engineering problems, including contact and
thermoviscoelastic problems.
OBJECTIVES:
(a) Understand viscoelastic models to establish the constitutive equations of viscoelasticity and to
analyze a viscoelastic behavior of engineering materials.
(b) Apply methods and general principles of viscoelastic stress analysis to solve engineering
problems.
(c) Learn about numerical solution techniques for viscoelastic stress analysis.
(d) Do a project associated with solving some engineering problems of viscoelasticity.

HOMEWORK :
Weekly written assignments and a term project.
TESTS :
Three quizzes. No final exam. The dates will be announced on class web page.
Make-up exams will be given only for properly documented medical excuses.
Only neatly written problems will be graded. A correct answer without a correct outline of the work
will not carry any grade.
GRADING:
Homeworks and project - 40%, quizzes - 20% (each)
ATTENDANCE:
Attendance is recommended. Content of missed classes is student’s responsibility.
ACADEMIC INTEGRITY :
You should work the homeworks individually, although you may consult with me or
other members of the class if questions arise. Checking answers is permitted, copying
other's solutions or code is not permitted. Scholastic dishonesty will not be tolerated
and will be prosecuted to the fullest extent.
ABET CRITERIA 2000 OUTCOMES ACHIEVED:
Knowledge of linear algebra and chemistry, depth in physics, advanced calculus, differential
equations and engineering sciences along with the ability to apply these toward solutions of
elementary mechanical engineering problems.
Ability to formulate and solve open-ended problems.
Ability to use modern computer based tools in mechanical engineering.
ASSESSMENT METHODS :
The course and instructor will be evaluated at the end of the semester using the BU
approved form.
