Aplicabilidade de uma máquina teste eletrodinâmica a molas não lineares
An eletrodynamic system for testing fatigue in springs is represented by a model which has two degrees of freedom. The simulation of the tester by a two degrees af freedom system with restoring force F =(α+βx²)x is made on an analog computer EAI – TR48 DES – 30. The favorable values of the spring …

Effects of cold metal transfer welding on properties of ferritic stainless steel
… technique, with comparisons made using tensile testing, hardness testing, impact testing, fatigue testing and microstructural characterisation. Experimental results show that grades such as EN1.4016 and EN1.4003 are more sensitive to the welding process due to a phase change to martensite …

Detection of Fatigue Crack Growth in a Simulated Aircraft Fuselage
<p>Acoustic emission (AE) nondestructive testing can detect fatigue cracks as they occur in complex structures. One use for AE has been in-flight detection of fatigue cracks in aircraft. The KC-135 aircraft were successfully monitored as early as 1979. The main problem with this and subsequent …

The Role of Slip System Activation on Ni-Based Superalloy High Temperature Fatigue
… It has been well documented that material fatigue is characterized by material microstructure, type of loading, and other parameters. Currently, research into the effects of fatigue on complex materials like nickel-based superalloys is being pursued. Previous research has found that …

Exploration of Wood DCB Specimens Using Southern Yellow Pine for Monotonic and Cyclic Loading
… cantilever beam (DCB) as a valid means for testing Mode I fracture energy in wood adhesive bonds. Southern yellow pine (SYP) adherends were used with epoxy and phenol formaldehyde (PF) impregnated films, providing two systems with different characteristics for investigation. An adhesive …
