Prediction of High Temperature Behavior of Open‐Cell Ceramic Foams Using an Experimental‐Numerical Approach

“…The resultant mean value is E ¼ 1 630 MPa. Based on the testing results of Figure 3a, a power law formulation [2,4] …”

“…with the stress factors A and b, the stress exponents n and c, the time exponent m, and the strain exponent l. The material parameters of the strain hardening model are functions of the time hardening model, see Naumenko et al [4] :…”

“…see Odqvist et al [2] For an arbitrary stress state, the von Mises stress s vM is used for isotropic materials in these two models for the equivalent stress [2,4] …”

“…There are many different models in the literature to describe the creep deformation behavior. [2][3][4] Detailed simulations of geometrical complex foams and the filtering process would require very large meshes and computational power. Thus, homogenized effective and stochastical foam structures of Abendroth et al [5] are used to investigate the creep behavior of such foams.…”

Metallien virumismurron ja virumisväsymisen mallintaminen

“…Vauriomekaniikkaan perustuva lähestymistapa muodostaa hyvän lähtökohdan, ja sitä on sovellettu useissa tutkimuksissa [1,4,11,12,13,25,27,34]. Tässä artikkelissa tarkastellaan etupäässä sekundääristä ja tertiäärivaiheen virumaa, joten yksinkertaisin mahdollinen sisäisten muuttujien joukko koostuu vain yhdestä skalaari-vauriomuuttujasta.…”
