With both void cavity and phase change considered, thermal performance of the heat pipe receiver was numerically analyzed under microgravity.
The model generalizes the Gurson model to account for both void growth and coalescence with explicit dependence on void shape and distribution effects.
The ability of ductile damage models to predict both void growth with shape change and void rotation is thus crucial for complex loading applications.
Both void fraction and bubble count rate data showed a local maximum in the developing shear layer, although the local maximum void fraction was always located below the local maximum bubble count rate.
The aim of this paper is to provide a homogenized criterion for porous ductile materials incorporating both void shape and plastic anisotropy effects.
It was possible to describe crazing stress and its temperature dependence when the factors of both void and fibril formation were taken into consideration.
Analyses of these data support an earlier observation that all stress states, whether tensile, compressive, shear or mixed, can affect both void swelling and interactions between irradiation creep and swelling.
This is attributed to a buckling instability driven by the residual thermal mismatch stress and induced by both void formation and a non-planar interface structure resulting from preferential diffusion along the Ni3Al grain boundaries.
Data for both voiding models shows that the organs that received the highest radiation absorbed dose were the gallbladder, upper large intestine, small intestine, liver, and urinary bladder at 143.0 ± 80.20, 74.50 ± 34.20, 65.50 ± 29.60, 64.40 ± 22.10, and 27.10 ± 11.70 μSv/MBq, respectively.
