Propagation of deformation bands investigated by laser scanning extensometry

On the PLC effect in strain-rate and stress-rate controlled tests–studies by laser scanning extensometry

“…In [32] the hopping type B bands (cf. [31,33]) are described as a perturbation of type A behavior. The propagative property is incorporated into the model by a second order gradient term (cf.…”

Finite-element and finite-difference simulations of the mechanical behavior of austenitic steels at different strain rates and temperatures

“…The jerky-flow phenomenon in alloys has been well studied experimentally, for instance by Beukel and Kocks (1982), Kubin et al (1992), Nagornih et al (1993), Toyooka et al (2001), Deryugin et al (2001), Casarotto et al (2003), Klose et al (2003), Nemat-Nasser and Guo (2005), and attributed to the formation of localized deformation bands at the meso scale. As a special case of such an anomalous behavior, Lüders band propagation is characterized by single displacement of macroscopic localization zone along the test piece.…”

Optoelectronic Techniques for Surface Characterization of Fabrics

“…Their displacement during a tensile test is studied thanks to a video camera. Fiedler Company, Grellmann et al (1997), Casarotto et al (2003) and Chmelik et al (2002) also use such methods. Marks which are normal to the tensile direction have reflective properties and are scanned by a laser beam.…”
