Zusammenfassung
Digital image correlation was used to study the mechanical behavior
of three materials: commercial aluminum, bovine pericardium and Cu�Al
11.2 wt.%�Be 0.6 wt.% shape memory alloy. These materials were
subjected to simple tension test using an MTS load frame with an
attached optical microscope. Displacement, force, strain data and
digital images of the sample's surface were acquired. Data and images
were post-processed in order to measure displacement vector fields
for each material. Local and global strain measurements were calculated
hence the young modulus was obtained for each material. The elastic
moduli were 60 GPa for aluminum, 160 MPa for bovine pericardium and
110 GPa for the CuAlBe austenitic phase and 27 GPa for the mixture
of austenite and martensitic phases.
