Popis:	In the present work Zr-based bulk metallic glassy samples with low aspect ratio (1:2) were deformed plastically at quasistatic loading conditions in order to study propagation of relatively homogeneous plastic deformation without clear shear localization in a dominant shear band that was observed in the samples with larger aspect ratio. Usage of low aspect ratio allows achieving large plastic deformations without fracture by forming multiple shear bands. The experimental results are discussed and compared with those of molecular dynamics and finite elements model computer simulation.
