“…For example, the flow rate is presented only with its thermally activated part, assuming to capture both dislocation drag and frictional behavior in the same flow rule. The model does not contain strain gradient extension [39], which could be used to study local scale defects, such as inclusions and carbides with a very small size. This was chosen due to the analysis being focused on the polycrystal behavior of the material in the scope of the current work.…”

A miniature pneumatic bellows device was designed for in-situ testing inside the scanning electron microscope. The device uses a pneumatic actuator to load the specimen and displacement is directly monitored with a linear variable differential transformer sensor. Its application allowed the direct monitoring of microstructural and defect evolution in materials at the micro scale. The data produced by this testing device, in combination with measurements from micro digital image correlation, were successfully used to model the crystal plasticity of a martensitic/bainitic steel at the microstructural length scale.
