Sammanfattning : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable, it is possible to have a large variety of deformation and mechanical properties depending on microstructure. LÄS MER
Sammanfattning : incorporation of new design materials – e.g. in order to promote lightweight design – oftenleading to significant changes in manufacturing conditions, which can be assessed in anefficient way by simulation rather than more expensive testing. LÄS MER
Sammanfattning : A microstructure level simulation model of cast iron machining based on micrograph image analysis has been developed. The simulation tool has been developed for theorthogonal machining process involving 2D representations of a range of cast iron microstructures. LÄS MER
Sammanfattning : AbstractTo strengthen the competitiveness the manufacturing industry strives for a continuousdevelopment of cost efficient manufacturing processes and improved product quality.These research and development issues are addressed by increasing the implementationof simulation tools based on finite element method (FEM).

Sammanfattning : The ever growing demand on reduced fuel consumption in modern aircrafts puts high requirements on manufacturers to reduce weight in all parts of the aircraft. With a total weight of up to one fifth of an aircraft’s total operating weight, ways to decrease the weight of the engine systems are continuously sought. LÄS MER
