  2. 16. Modelling the viscoplastic properties of carbon black filled rubber : A finite strain material model suitable for Finite Element Analysis

    Author : Rickard Österlöf; Leif Kari; Alan Muhr; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcing fillers; rubber; finite strain; viscoplastic; förstärkande fyllmedel; gummi; finita töjningar; viskoplastisk; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : An increased environmental awareness, legal demands and the large part of total costs attributable to fuel cost are all incentives for the automotive industry to reduce fuel consumption. The optimal driveline to enable this reduction depends on the operational conditions and the available infrastructure. READ MORE

  4. 17. Application of Differential Geometry to Elasticity and Corresponding Discrete Models

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical systems; differential geometry; isoparametric four-node elements; Lie groups; non-linear elasticity; elasticity; finite element method;

    Abstract : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. READ MORE

  7. 20. Alternatives for Finite Element Analysis of Blade Forging

    Author : Behzad Soltani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual stresses; blade forging; flow approach; metal forming; quasistatic implicit; dynamic explicit; forging; solid approach; finite element method; closed die forging;

    Abstract : This thesis is a theoretical and numerical study of the weaknesses and capabilities of alternative finite element procedures for simulation of the blade forging problem and also an analysis of the practical aspects of that process. An overview is presented of the finite element method for non-linear problems with elastoplastic constitutive relations, focusing on quasistatic implicit and dynamic explicit approaches. READ MORE
