A new technique to measure the dynamic fracture toughness of solids
Polymer Testing, 2023 We propose and assess a new experimental technique to measure the fracture toughness of engineering materials and its sensitivity to strain rate. The proposed method is based on a ring expansion technique and it overcomes the limitations of current ...

Investigation on the Strain Rate Sensitivity of Polytetrafluoroethylene
DEStech Transactions on Engineering and Technology Research, 2018 Strain rate sensitivity of polytetrafluoroethylene(PTFE) across strain rate range from 10-3 to 106 s-1 was investigated. For quasi-static state of strain rates from10-3 to 10-1 s-1, the samples were tested using universal material testing machine. The values of compression strength and Young’s Modulus were calculated from the experimental results.

Physical nature of strain rate sensitivity of metals and alloys at high strain rates [PDF]
Journal of Physics: Conference Series, 2018 The role of instabilities of plastic flow at plastic deformation of various materials is one of the important cross-disciplinary problems which is equally important in physics, mechanics and material science. The strain rate sensitivities under slow and high strain rate conditions of loading have different physical nature.

Thickness-Dependent Strain Rate Sensitivity of Nanolayers via the Nanoindentation Technique
Crystals, 2018 The strain rate sensitivity (SRS) and dislocation activation volume are two inter-related material properties for understanding thermally-activated plastic deformation, such as creep. For face-centered-cubic metals, SRS normally increases with decreasing

Modeling strain rate sensitivity and high temperature deformation of Mg-3Al-1Zn alloy
Journal of Magnesium and Alloys, 2019 Increasing the plastic deformation temperature of Mg alloys results in higher strain rate sensitivity, easier activation of secondary slip modes, and impeded twinning. In this study, the strain rate sensitivity is estimated for each deformation mode, and

Dynamic nanoindentation testing: is there an influence on a material’s hardness?
Materials Research Letters, 2017 Modern nanoindentation devices are capable of dynamic experimentations, which allow us to exploit instrumented hardness tests extensively. Beside the assets of recording mechanical properties continuously over displacement, there are ongoing debates ...

Effect of oxygen contents on strain rate sensitivity of commercially pure titanium [PDF]
MATEC Web of Conferences, 2020 In this study, we have investigated the effect of oxygen contents on strain rate senstivitiy (SRS) within Gr. 1 and 4 commercially pure titanium (CP-Ti). The SRS was evaluated in multi-scales using macro-scopic tensile test with constant strain rate (CSR)
