Abstract
This paper presents seventy new experimental results from PMMA notched specimens
tested under torsion at 60 C. The notch root radius ranges from 0.025 to 7.0 mm. At this
temperature the non-linear effects previously observed on specimens of the same material
tested at room temperature strongly reduce.
The averaged value of the strain energy density over a control volume is used to assess
the critical loads to failure. The radius of the control volume and the critical strain energy
density are evaluated a priori by using in combination the mode III critical stress intensity
factor from cracked-like specimens and the critical stress to failure detected from semicircular
notches with a large notch root radius
