   Sammanfattning : Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. LÄS MER

3. 2. Numerical simulation of residual stresses in a weld seam : An application of the Finite Element Method

   Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Maciej Maczugowski; [2017]
   Nyckelord :Finite element method; residual stresses; temperature distribution; fatigue life; weld power; time step; T-joint weld model; Butt weld model.;

   Sammanfattning : Articulated haulers are fundamental equipment to transport material. The load carrying structure on a hauler consists mainly of welded frames. During welding of the frames high residual stress will be introduced. These stresses may have a significant impact on the fatigue life of the frames. LÄS MER
