Providing accurate model input data requires statistically significant sample sizes; procuring enough material for these tests can prove challenging and costly, presenting a need for reduced specimen geometry. Further, developing and validating material models requires an easy to use and repeatable system capable of producing quantitative and qualitative insight. The authors present a universal thermomechanical load frame that enables meso-scale in-situ testing on miniaturized samples with optical, SEM, AFM, confocal, and μCT imaging to name a few. Available grips and add-ons such as temperature chamber and nanopositioning stage allow myriad test procedures. Global displacement sensors span the nanometer to millimeter length range, augmenting digital image correlation to provide closed loop control. High resolution force measurements are captured with a single sensor from micro- to kilonewtons. An example case analyzes the size-property relationship at this scale and implications for model development. Additional use-cases taking advantage of the system are described.
