Lifetime Fatigue

HBM, a wholly-owned subsidiary company of Spectris plc, a group specialized in precision instrumentation and electronic controls, announced the release of ANSYS 2020R1 nCode DesignLife, the leading brand for engineering data analysis solutions with special concentration in fatigue and durability.

This book focuses on the damage, fracture and fatigue of ceramic-matrix composites. It investigates tensile damage and fracture, fatigue hysteresis, and the properties of interfaces subjected to cyclic fatigue loading. Further, it predicts fatigue life at room and elevated temperatures using newly developed damage models and methods, and it analyzes and compares damage, fracture and fatigue behavior of different fiber performs: unidirectional, cross-ply, 2D and 2.5D woven.

The accumulation of damage and the development of fatigue cracks under the influence of loads is a common phenomenon that occurs in metals. To slow down crack growth and ensure an adequate level of safety and the optimal durability of structural elements, experimental tests and simulations are required to determine the influence of various factors. Such factors include, among others, the impact of microstructures, voids, notches, the environment, etc. Research carried out in this field and the results obtained are necessary to guide development toward the receipt of new and advanced materials that meet the requirements of the designers. This Special Issue aims to provide the data, models and tools necessary to provide structural integrity and perform lifetime prediction based on the stress (strain) state and, finally, the increase in fatigue cracks in the material.

This book synthesizes the results of author’s researches and results from known publications in the field of surface layers fracture of cyclical contacting bodies (machine parts). The calculation models and calculating procedures of stress-strain states of cyclically contacting solids with cracks, have been proposed.

Chronic headaches…brain fog…fatigue…weight gain…insomnia…gut pain…autoimmune conditions. We may think these and other all-too-common modern maladies are due to gluten intake or too much sugar or too little exercise. But there is another missing piece to the health puzzle: Proper hydration.
