Compilation of the two stress state environments has generated a biaxial failure surface criterion yielding the residual tensile strength of single fibers when subjected to a specific grade of shear stress.
It made an excellent suggestion but couldn't see further than a few surface criteria to assess compatibility.
For this purpose, a surface roughness criterion for detecting crack initiation at different applied loads is introduced.
The advantage of the sphericity criterion with respect to the surface criterion proposed in [4] is that it guarantees the invariance to translation and also to scaling and rotation.
Specific site selection should be based on a suitability analysis, a proper inventory of potential sites, an assessment of the fate of the injected CO2 and a capacity determination, together with surface criteria such as CO2 capture and transport.
They are carefully designed according to many surface criteria amongst which wear resistance is the most important.
In order to archive improved hemocompatibility of the evaluated alloy, which is closely associated with corrosion resistance and wettability of the surface – criteria for optimum choice of the surface modification option – the following preliminary tests were selected: potentiodynamic, potentiostatic, impedance and wettability as well as surface energy.
Cell surface markers showed positive for CD105, CD29, CD13, CD73, and HLA class I and negative for CD34, CD45, CD31, and HLA class II, which met the cell surface criteria for MSC [ 31].
The hyperbolic composite interface model consists of a single surface yield criterion, which is a direct extension of Mohr-Coulomb criteria with cut in tension region and a cap in compression region.
The IPCM avoids an estimate of the Born radius by employing an electron density criterion for defining a surface, not necessarily spherical, enclosing the species.
