Course Description
Various protective materials including body armor, helmets, and specialized suits are essential to saving lives and minimizing body injuries under extreme dynamic conditions. To advance the protective materials, fundamental understanding of material deformation behavior at very high rates is crucial. This course will provide basic understanding of materials science and high-strain-rate mechanics relevant to such extreme conditions. Potential material platforms with tailored micro- and nano-structures will be introduced to learn more about the current trend to discover novel material behaviors that could dramatically enhance protective performance. Furthermore, this course will introduce various dynamic mechanical characterization techniques and their applications.

Academic Honesty: Academic dishonesty, in any form, will not be tolerated and you are responsible for educating yourself about the University’s official policy on academic honesty. Following is a summary – you can read it in full at http://www.umass.edu/ombuds/honesty.php/. If an instructor finds that a student has violated the University’s Academic Honesty Policy, the instructor has the right to lower the student’s grade, or even to fail the student for the course. Students have the right to appeal such a grade penalty by an instructor. The University Academic Honesty Board, which must be notified by instructors of any grade penalty, reviews all student appeals. The Board may sustain or recommend modification of the penalty given by the faculty member, or may recommend sanctions exceed those originally given, such as suspension or expulsion from the University. The Board may also recommend sanctions for offenders who have committed multiple violations of the Academic Honesty Policy but who have not appealed the faculty members’ decisions.

Diversity Statement: We are all members of an academic community with a shared responsibility to cultivate a climate where all students/individuals are valued and where both they and their ideas are treated with respect. The diversity of the participants in this course is a valuable source of ideas, problem solving strategies, and engineering creativity. If you feel that your contribution is not being valued for any reason, please speak with me privately. You may also speak with Dr. Paula Rees, Assistant Dean for Diversity (rees@umass.edu, 413.545.6324, Marston 128), submit a comment to the box on the door of Marston 128, or submit an anonymous comment online http://tinyurl.com/UMassEngineerClimate .

Inclusivity: The diversity of the participants in this course is a valuable source of ideas, problem solving strategies, and engineering creativity.
