Verification of our deformation member for measuring axial force under torsional dynamic load
Šulc, Petr ; Pešek, Luděk ; Štěpánek, Ivo ; Šnábl, Pavel ; Bula, Vítězslav
This paper deals with experimental testing of hard rubbers under torsional harmonic loading on an axial torsional servohydraulic testing machine Instron 8852. In evaluating these experiments, we focused on obtaining axial forces and elongation, which is a confirmation of the so-called Poynting effect under torsional loading. An important result from these experiments is a comparison of axial forces from this device with the results from our designed and assembled torsion device with a deformation member for measuring axial forces, which brings us some verification of this device.
Analytical, numerical and experimental analysis of Poynting´s effect coused by large torsion of a prismatic cylinder
Poživilová, Alena ; Plešek, Jiří
Poynting effect occurring at large torsion of prismatic bars is investigated. Results of analytical and numerical solutions are compared against recent experimental data.
Modelování torze a kombinovaného protažení s torzí hyperelastických válcových vzorků
Poživilová, Alena ; Plešek, Jiří
Sress effects in an incompressible hyperelastic cylindrical specimen are specified for the torsion test and combined elongation-torsion tests. The results include the well-known Poynting effect.
