Defect dependent dynamic nanoindentation hardness of copper up to 25 000 s-1
Hendrik Holz, Lalith Kumar Bhaskar, Tobias Brink +4
Metals exhibit an upturn in strength at strain rates of approximately 1000 s-1 - 3000 s-1, governed by rapid dislocation multiplication, interactions and storage. This phenomenon i…
Scale-bridging dislocation plasticity in MgO at room temperature
Jiawen Zhang, Zhangtao Li, Yuwei Zhang +7
Dislocations in ceramics have recently gained renewed research interest, in contrast to the traditional belief that ceramics are inherently brittle. Understanding dislocation mecha…
Filling a gap in materials mechanics: Nanoindentation at high constant strain rates upto
Lalith Kumar Bhaskar, Dipali Sonawane, Hendrik Holz +12
A central focus in high strain rate research is understanding the dynamic behavior of materials at strain rates where a strength upturn is observed. While strength upturns at strai…
Probing Elastic Isotropy in Entropy Stabilized Transition Metal Oxides: Experimental Estimation of Single Crystal Elastic Constants from Polycrystalline Materials
Lalith Kumar Bhaskar, Niraja Moharana, Hendrik Holz +3
Single Crystal Elastic Constants (SECs) are pivotal for understanding material deformation, validating interatomic potentials, and enabling crucial material simulations. The entrop…
