Does isostatic and aero graphite same? 


Best insight from top research papers

Isostatic graphite and aerostatic graphite are distinct materials with unique properties and preparation methods. Isostatic graphite is prepared by mixing raw materials with carbon black, undergoing isostatic shaping, and utilizing interphase carbon microspheres to enhance structure uniformity and mechanical strength . On the other hand, aerostatic thrust bearings utilize isotropic porous graphite plungers to ensure uniform porosity, consistent permeability, and high bearing capacity, stability, and static stiffness . The preparation of isostatic graphite involves processes like pulverizing, calcining, kneading, extruding, and impregnating to achieve a product with improved volume density, strength, and performance . Therefore, while both materials involve graphite, their specific characteristics, applications, and preparation methods differentiate isostatic and aerostatic graphite.

Isogeometric analysis on sandwich plates5 answersIsogeometric analysis (IGA) has been used in several papers to analyze the static, dynamic, and buckling behavior of laminated and functionally graded (FG) sandwich plates. The use of IGA allows for the implementation of nonpolynomial shear deformation theories (NPSDT) and third-order shear deformation theories (TSDT) in the analysis, which consider the nonlinear distribution of transverse shear stresses and satisfy the transverse shear deformation conditions at the top and bottom surfaces of the plates.
