Properties of a Bi-Metal Laminate Composite Engine Gasket
For this application we extended the boundaries of conventional Holographic
Moiré to new heights. We were able to measure displacements in the
nano-meter range.The Bi-Metal Laminate composite that was measured for this
experiment had a thickness of 0.008"(~200 microns). The set up
that was used can be seen in the images below. An optical bench was attached
to an Instron machine, a special fixture was designed to illuminate the
surface while the piece experienced the compression. The field of view was
480 x 360 microns and we had resolution in the micron range. With
the power of the HMSA we were able to obtain strain values and create graphs
that contain the loading and unloading properties of the Bi-Metal Laminate
Composite along with a 3-D representation of the strain field at specific
loads.
