Abstract

In this study, applied tensile plastic preload in 2024 and 7075 Al-alloys plates with central hole generate residual stress field. Around the central hole compressive residual stress was generated when finite element method was used and Von Mises criterion was applied for plastic preload. The level of compressive residual stress increase in increasing of applied plastic preload. Fatigue life and fatigue crack growth rate (FCGR) depend on the level of plastic preload. Consequently fatigue life increase and FCGR decrease. No high effect of level of applied plastic preload was shown for 7075 Al-alloy on fatigue behavior.

Abstract

Mg-Al-LDHs with different Mg/Al mol ratio were studied. Adsorption of different organic substances on the layered double hydroxides (LDHs) of different composition was studied. Fatty alcohols, phenols and naphthalene derivatives were used as a sorbates. The structure changes, taking place because of this process, was explored by X-ray method. It has been found, that at the adsorption of such substances as alcohol and phenols the anion exchange take place. After the sorption the specific surface and inner distance of LDHs were measured. The mechanism of structure change was proposed.
