… of flexural buckling of a framework brace towards compression force and bending, ?the control of a framework brace towards tension force and bending, ?the control of a column against compression by a pure normal force, ?and the control of a welded joint between a framework brace …
att b?ja st?nger till t?ltk?ta
This thesis is my exploration of the immaterial heritage that is the craft of bending of ?dn?ris? out of spruce. It’s a broken tradition that is scarcely described, mainly through Yngve Ryd’s report T?ltk?tor (1999) that contains interviews with two knowledge keepers, Nilas …

… program to get data for movements and symmetry in flexion/extension, lateral bending and axial rotation of the vertebrae. The symmetry and movements of the back has been compared before and after acupuncture treatment. The kinematic results of the back showed that the horse …
… 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 equipment is …
… to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these …

En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare
… The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric …
… element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection. First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were …
… material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of …
… Element analyzes. The dimensioning of the axle is currently based on the bending stress, but the author’s opinion is that the axle should be dimensioned considering the equivalent stress. Wear and pretension had large influence on the strain along the axle, but almost no …

… the surface layers. The results has shown that by using this method both the bending stiffness and surface properties are improved, or a lower grammage paper is obtained with maintaining quality. Simultaneous forming can also be used to stratify fillers in layers where they are …
… to the muscle groups pronator and extensor which affect stretching and bending of the digits, elbow and knee. The variation is connected to conditions of locomotion and musculoskeletal stress and indicates different usage of dogs. The burial ground of Skateholm I-II demonstrates …
I samband med att intresset för att bygga högre trähus har ökat så krävs nya lösningar för att t.ex. kunna möta efterfrågan på stora öppna ytor och långa spännvidder. Träbjälklag med lång spännvidd har dock oftast svårigheter med att klara kraven på svikt och vibrationer. Ett …
… thicker plates we had to come up with a theory for calculation off cutting and bending. Then we had to compare our theory with the reality, and that was done by measuring the pressure on the working cylinder when the machine was operating. Those results showed that our theory …
… to find out which limitations there are. Bolted joint has to exceed a minimum bending strength and the bolts have to be made out of steel and their strength has to be at least 10.9. Today Rolls-Royce use ten bolts per propeller, five on each side of the blade. To analyze the …
