In recent decades, specimens with hat-shaped geometry have been used to study materials with respect to their shear behavior including strain localization and adiabatic shear banding (ASB). However, the interpretation of the experimental results is still not straightforward because of the complex stress distribution in the shear region of the specimen. More comprehensive use of the hat-shaped specimen is possible when a better description of the distribution and evolution of the stress state in the specimen is available. This paper presents the results of dynamic and static experiments on Ti-6Al-4V and numerical simulations in ABAQUS/Explicit. The stress, strain and temperature distribution and evolution is examined for specimens with varying dimensions. The aim is to identify the important factors that affect the experimental results.
