A Miniaturized In Situ Tensile Platform under Microscope
Abstract: Aiming at the
mechanical testing of three-dimensional specimens with feature size of
centimeter level, a miniaturized tensile platform, which presents compatibility
with scanning electron microscope (SEM) and metallographic microscope, was
designed and built. The platform could accurately evaluate the parameters such
as elastic modulus, elongation and yield limit, etc. The calibration
experiments of load sensor and displacement sensor showed the two kinds of
sensors had high linearity. Testing of transmission error and modal parameters
showed that the platform presented good following behaviors and separation of
resonance region. Comparison tests based on stress-strain curve were carried
out between the self-made platform and the commercial tensile instrument
(Instron) to verify the feasibility of the platform. Furthermore, the in situ
tensile experiment under metallographic microscope was carried out on a kind of
manganese steel.
