Johnson–Holmquist damage model - Wikipedia
The Johnson-Holmquist material model (JH-2), with damage, is useful when modeling brittle materials, such as ceramics, subjected to large pressures, shear strain and high strain rates.
A modified JH2 model with improved strength model, damage …
Nov 1, 2022 · Considering that the JH2 model is stronger than the HJC model but less complex than the RHT model and there are still some non-negligible defects to be solved, a modified JH2 (M-JH2) …
The pseudokinase domain of JAK2 is a dual-specificity protein kinase ...
Here, we show that JH2 is a dual-specificity protein kinase that phosphorylates two negative regulatory sites in JAK2, Ser523 and Tyr570. Inactivation of JH2 catalytic activity increased JAK2 basal activity …
JH-2 constitutive model of sandstone for dynamic problems
Feb 9, 2024 · Quantitative and qualitative comparisons demonstrate that the JH-2 model agrees well with both experimental and analytical results. Limitations of the model are also highlighted, particularly...
(PDF) Determination of Parameters of Johnson-Holmquist-II (JH-2 ...
Aug 1, 2021 · Firstly, some mechanical properties of red sandstone specimens are tested, including quasi-static compression, SHPB dynamic compression test and Brazilian disk splitting test, and the …
JH-2 Model Integration in DYNA3D
This report describes the implementation of the Johnson-Holmquist II (JH-2) constitutive model for brittle materials like ceramics into the DYNA3D finite element code. The JH-2 model accounts for pressure …
Covalent Modification of the JH2 Domain of Janus Kinase 2
Probe molecules that covalently modify the JAK2 pseudokinase domain (JH2) are reported. Selective targeting of JH2 domains over the kinase (JH1) domains is a necessary feature for ligands intended …
Study on parameter acquisition and optimization methods of JH-2 ...
Feb 1, 2023 · In this study, based on AD995 and sapphire, the method of obtaining and optimizing the key parameters of the Johnson-Holmquist constitutive model (JH-2 model) for typical brittle materials …
Quantitative and qualitative comparisons demonstrate that the JH‐2 model agrees well with both experimental and analytical results. Limitations of the model are also highlighted, particularly...
