Fracture Mechanics and Corrosion Fatigue
The development and current state-of-the-art in fracture mechanics in relation to studies of environment-enhanced fatigue-crack growth (corrosion fatigue) and fatigue-crack growth per se are reviewed. Patterns of response of materials to different loading and environmental conditions are considered in terms of the probable mechanisms for environmental embrittlement. The usefulness of the fractu...
متن کاملFatigue fracture of hydrogels
Rapid advances are taking place to develop hydrogels of high stretchability and toughness, but fatigue fracture has not been studied for any hydrogels. This negligence hinders the development of hydrogels and their applications. Herewe initiate a study of fatigue fracture of hydrogels.We choose polyacrylamide hydrogel as a model material. To place fatigue fracture in context, we apply monotonic...
متن کاملStress Concentrations , Fatigue , Fracture
The fundamental topic in this document is the development of cracks in steel. For structures subjected to cyclic loads, such cracks can develop over time and ultimately reach the size at which some dramatic failure occur. While this problem is rare in structures made of “mild steel,” the use of “high tensile” steel changes that situation. It is straightforward to double the strength of mild ste...
متن کاملFatigue Fracture of the Fibula
Fatigue, or stress, fractures have been described as occurring in many situations and at widely differing ages from 15 months to 64 years. Most have occurred in young adults, particularly soldiers in training and athletes. Although fatigue fractures usually occur in weight-bearing bones, in particular the metatarsals and tibia, they also occur in the fibula, and have even been described in the ...
متن کاملMechanical fatigue and fracture of Nitinol
Nitinol, a near equiatomic intermetallic of nickel and titanium, is the most widely known and used shape memory alloy. Owing to its capacity to undergo a thermal or stress induced martensitic phase transformation, Nitinol displays recoverable strains that are more than an order of magnitude greater than in traditional alloys, specifically as high as 10%. Since its discovery in the 1960s, Nitino...
