Strength of Materials And Damage Assessment
نویسنده
چکیده
The physical interpretation of the service life of a material that is under load requires the direct study of evolution of its structure, analysis of connection between elementary phenomena of plastic deformation and damage, and establishing the damage accumulation relationships. The development of increasingly precise methods for studying the microstructure and identifying the defects is associated with the increase of severity of requirements on operation conditions and safety as well as the economic effectiveness of the mechanical structures. Therefore, the problem of determining a change of the damage level in solids becomes more and more urgent in the course of time.

متن کاملEffects of Waste Fibers Stabilizers on the Draindown and Moisture Damage Sensitivity Properties of SMA Mixtures
Waste fibers produced from manufacturing processes are a byproduct commonly deposited in storing yards and/or landfills and thus results in many serious environmental problems in Iran. If these waste materials could be advantageously put to practical use in any application, it would reduce the burden on the environment and landfills. This paper compares the performance of the stone matrix aspha...
