Abstract Due to very significant improvements in the mechanical performance of solid wood, densification after partial or full delignification has received renewed attention. While studies predominantly focus on isolated cases, e.g., one wood species densified anatomical direction, systematic investigations effect structure process are seldom performed. The present study compares deformation pa...

OBJECTIVE This study examined predictors of relationship stability over 5 years among heterosexual cohabiting and married African American couples raising an elementary-school-age child. The vulnerability-stress-adaptation model of relationships (Karney & Bradbury, 1995) guided the investigation. Contextual variables were conceptualized as important determinants of education and income, which i...

An investigation of the effects of fatigue on A533B steel under constant load amplitude is reported in this paper. It was found that the plastic strain of the sample accumulated logarithmically with the number of stress cycles after initial fatigue softening. Based on the fact that plastic strain is often linearly related to the coercivity of material, at least for small changes of H c , a phen...

An analytical model that allows prediction or reproduction of the overall stress-strain relationship of a high performance cementitious composite in tension is presented. Through consideration of stochastic character of the composite microstructure, the model captures the sequence of crack formation and the load fluctuations that are characteristic for the process of multiple cracking. The prop...
