tensile properties of cast iron
… direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines. In order to achieve these requirements it’s necessary to increase …
… Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to …
… each other for FEM and the analytic analyze. At drift all bolts were under the tensile strength of 750 MPa but when using ice loads some bolts started to deform. A new concept for the bolt connection was tested. Again the stress in the bolts stayed under the tensile strength at …
… then help Wenmec to decide which electrode that is the most cost effective. Tensile testing, impact testing and fatigue testing were performed on the weld joint samples. The hardnesses, microstructures, failure zones and chemical composition were examined with optical microscopy …
… hardening and 2244 for induction hardening. To compare the different steels, tensile strength, bending strength and microhardness were tested. In the beginning, the materials were to be case hardened or induction hardened. Hägglunds use these methods today, and all necessary …
… and the decider of dimensions and design when the materials yield strength and tensile strength was too low and therefore essential. A number of attempts were made to increase the safety factor by adding both two and three keys to the keyed joint, but without success. With the …

… on the subject. The abrasive wear and other material characteristics such as tensile strength, compressive strength and elongation of POM and an alternative material for 3D-printing, Ultem?, an amorphous thermoplastic polyetherimide are discussed. These material characteristics …
… today’s constructions. A system of joists has to be dimensioned, besides the tensile strength dimensioning, be dimensioned against excessive deflection and spring when someone is walking across the floor. To achieve a stiffer floor it can be constructed with higher rafter …
Sammanfattning I en pappersrulle är de yttre lagren utsatta för dragspänning. Om det finns variationer i rullens diameter i form av valkar finns det risk för att papperet förlängs irreversibelt i dessa positioner och orsaka slappa stråk. Den deformation som uppstår vid långvarig …
… clean knit construction design to avoid problems asdelamination and decreased tensile properties. In addition, the chemical composition ofpolyurethane foam used in the process of lamination has been known for causing malicious damagefor humans as well as the global environment …
… as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE). Another aspect in this thesis analysed is the possibility to incorporate …
… The report also includes information about other tests conducted, such as tensile- and tear strength, wash resistance and color change. These measurements are made on those products which have shown satisfactory performance in regards to the fire tests.Among the nine products we …
… of the light beams act as thin sheet metal nailed and glued to take up the tensile forces that can arise in the construction, the sheet metals also diffusion barriers. On top of the light beams are sheet plywood nailed and glued in order to take up all the pressure forces …
Syftet med projektet var att undersöka hur homogeniserings förhållanden (tryck antal passager och därmed energiinsatsen) vid framställning av MFC (mikrofibrillär cellulosa), från enzymatiskt förbehandlade pappersmassafibrer påverkar hållfastheten av papper förstärkt med MFC …
