“…The effect of wood type, preservative type and concentration (treatment), and the adhesive system was investigated using a design selected according to D-optimality (Guttorp and Lindgren 2009). In the field of design of experiments and optimal designs, D-optimality is a popular optimality criterion (Redhe et al 2002; Chen et al 2010; Mosayebi Omshi and Shemehsavar 2018; Yeesa et al 2019). In this study, 16 design points (Table 2) were randomly selected from 36 candidate design points sequentially generated and improved by exchange method using Minitab Software v.18.…”

The fundamental factors responsible for the complexities in adhesive bonding of preservativetreated wood are predominantly wood species, preservative composition, and adhesive system. It is post-effect of these factors that process variables such as assembly times and bonding pressure exert secondary influences on adhesive-bond development in preservative-treated laminates. Hence, this study investigated the effect of copper azole (CA) and disodium octaborate tetrahydrate (DOT) impregnations on E. grandis heartwood (HW) and sapwood (SW) bonding with melamine-urea-formaldehyde and polyurethane adhesives. Based on the adhesives and bonding conditions investigated, the CA and DOTtreated E. grandis laminates do not satisfy at least one of the shear strength and delamination requirements according to EN 14080:2013. Contrary to delamination, shear strength was significantly affected by the HW-SW difference. This study established the basis for further considerations on adapting bonding conditions for improved adhesivebond performance in CA and DOT-treated E. grandis laminates towards manufacturing durable hardwood composite for tropical and subtropical environments.

“…The design methods of ADT include the D-optimal, C-optimal, and M-optimal criteria. Omshi et al [43] used the D-optimal criterion to conduct a constant stress accelerated degradation testing with a degradation path following the inverse Gaussian process. They obtained the optimal sample allocation for each stress level and determined the effect of stress level on the objective function.…”

High reliability and long life are typical requirements for mechanical products. The performance requirements of mechanical products are increasing as science and technology develop, and the environment and working stress they bear are becoming more diverse. This issue has become one of the bottlenecks for mechanical products in lifespan and reliability generally. The aim of this study is to categorize, examine, and review the most applicable accelerated testing methods for mechanical products. The research status of accelerated modeling methods, statistical analysis, and design optimization of accelerated degradation testing(ADT) technology are reviewed. On the basis of literature analysis, the deficiencies and possible development directions of ADT were summarized and prospected. This work is anticipated to serve as a reference and provide important insights into the reliability of mechanical products.
