Objectives
The objective of this course is to introduce students to
different aspects of measuring deformation, strains, and stresses, for
developing a mechanistic understanding of both the material and the structure
behavior. Students will be introduced to recent advances in experimental
techniques for full field displacement measurements and the associated
underlying concepts. Traditional methods for point wise measurements (e.g.,
strain gauges) will be also addressed. Students will utilize these techniques
to understand the performance of a structure of their choice, as well as
new conceptual structures that are made of multilayers and adhesives.
Such experience is vital in building the engineering factual base of knowledge
for students who will work in microelectronics, aerospace and auto industry,
and other manufacturing and service sectors. You
will be introduced to:
-
Experimental concepts in solid mechanics
-
Various methods for measuring applied forces and
displacements
-
Point wise displacement measurements
(e.g., strain gage)
-
Transducer Applications (e.g. LVDT, Strain gages,
Piezoelectric elements)
-
Application of Wave optics to Material
Research
-
Full field displacement measurements (e.g. photo
elasticity, grid and moiré, digital image correlation)
