Fatigue 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 کاملThermal Stress Resistance to Fracture and its Relation to with Resistance to Thermal Fatigue and Shock
Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...

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 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...
