Long‐term strength of aesthetic restoratives

Journal of Oral Rehabilitation, 1998
Glass‐ionomer cements have established an important role in clinical dentistry since their introduction over 20 years ago. More recently, in an attempt to enhance the strength of the material, resin additions have been made to conventional glass‐ionomer cements. This study established the long term flexural strength of two hybrid glass‐ionomer cements,

Long‐term strength of ceramics for biomedical applications

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2004
AbstractThe influence of slow crack growth on the initiation of radial cracks at the lower surfaces of ceramic layers bonded to polymeric substrates is studied, with particular relevance to biomechanical systems, e.g., dental crowns and hip replacement prostheses.

Assessment of Long-Term Strength of Rocks

Key Engineering Materials, 2017
In relation to extraction of coal seams at significant depths, the issue of protection of safety equipment against pressure exerted by rock becomes very important. In many surveys of the effects of pressure exerted by rock it was demonstrated that the intensity of stress around the mine works increases the greater the depth of the mine works.

Long-term strength of reinforced composites

Mechanics of Composite Materials, 1989
A criterion of long-term strength was proposed for composite materials. The criterion can be used to calculate time to failure for arbitrary loading programs. It was shown that the criterion provides for good agreement with the experimental data not only in the cases of instantaneous and long-term static loadings, but also for fatigue loading in ...
