Cold roller bending is commonly used for bending straight members with hot rolled wide-flange sections to create arches. This process induces plastic deformations along the member, so that it can acquire the desired curvature. The resulting residual stress distribution is different from the wellknown residual stress pattern due to hot rolling. Extensive studies have shown that the influence of ...

AIM The aim of this study was to compare the effects of preparation with conventional stainless steel Flexofiles and Gates Glidden burs versus nickel-titanium GT rotary files in the shaping of mesial root canals of extracted mandibular molars. METHODOLOGY A total of 54 canals from 27 mesial roots of mandibular molar teeth were prepared using one of two methods by novice dental students. One c...

A Eurocode-compliant design approach was developed for the of thin-walled cold-formed steel sections which combines AISI S100-16-Direct Strength Method (DSM) with provisions EN 1993-1-3. The new transfers cross-sectional resistance determined acc. to DSM based on numerical elastic buckling analyses gross cross-section into global member verification Additional factors were introduced optimize a...

The mechanical properties of dual Phase steels (DP steels) are strictly related to the spatial distribution and the geometry of the two phases composing the steel, ferrite and martensite. Due to the high costs to obtain images of sections of steel samples, one important industrial problem is the reduction of the number of 2D sections needed to build and simulate a geometric model which may repr...
