Effects Of The Cryogenic Wire Brushing On The Surface Integrity And The Fatigue Life Improvements Oft ambient and low temperatures were investigated. It was found that the cold work hardening generated by the cryogenic brushing increases the levels of the compressive residual stresses comparatively to the dry brushing and therefore, results on higher nucleation fatigue lifetime of mechanical compo

Surface Integrity In High Speed Machining Of Alloydeformed grains in the obtained surface, turned in the direction of the cutting tool passage. X-ray diffraction confirms the intense deformation of the machined surface and shows a crystallographic texture modification. The metallurgical observations do not reveal any phase transformation and no evi

The present and the new HFR-Petten SANS facilityrole for obtaining structural information. Small-Angle Neutron-Scattering (SANS) is one such scattering technique by which one can obtain structural information of the material being studied. Structural information here means size and form of the object under investigation. In a SANS experiment one

Welding Effects On Thin Stiffened Panelse of welded structure. In steel industry and particularly in shipbuilding, during these last few decades, thin plates are used more and more in ship construction in order to lighten the structure weight. Unfortunately, excessive distortions occurred on these thin stiffened panels and straightening w

Phase Transformation And Damage Elastoplastic Multiphase Model For Welding Simulationstudy of damage concept in the multiphasic behavior, which occurs by welding process. The core of models or constitutive equations is the coupling between ductile damage, small strain elasticity, finite visco-plasticity and phase transformation. Based on the theory of thermodynamics and continuum da

Interaction of Residual Stress with Mechanical Loading in a Ferritic Steelthe application of a “local approach” to determine the change in applied load to cause fracture is described. Then the R6 defect assessment procedure is presented. The effect of tensile residual stress on brittle fracture of ferritic steel type A533B at -150ºC is explored. The modified J-integral, J
