Abstract: This thesis
describes the design of a low-cost system of tests to characterize mechanical properties
in soft structures. More specifically, we focus on testing mesoscale structural
components (which we call structural volume elements) from which a larger structure
might be constructed. The mechanical properties of a structural volume element are
determined both by its material prope... read morerties and by its geometry. The testkit provides an
easy-to-implement means of characterizing force-displacement relationships (e.g.
compression, shear, bending) for nonlinear materials in the presence of large
deformations and buckling instabilities. The testkit includes both hardware and software
components. The purpose of the hardware is to apply loading conditions to a small
structural volume element, approximately 1 cm3 in volume. The purpose of the software is
to measure the displacements that occur as loading
changes.
