  1. 1. Dynamic analyses of structures with applied rubber

    University dissertation from Chalmers University of Technology

    Author : Magnus Alvelid; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastkroppsmekanik; Solid mechanics; Fractional calculus; Viscoelasticity; Series expansion; Optimization; Finite;

    Abstract : The aim with the present thesis has been to develop efficient, practical and accurate methods in order to model rubber in dynamic analyses, with emphasis on passive constrained layer damping materials. A fractional order viscoelastic constitutive model is mapped onto experimental data from a measurement standard using a vibrating beam technique. READ MORE

    Abstract : Mechanical Behaviour of Adhesive Layers Methods to Extract Peel and Mixed Mode Properties TOBIAS ANDERSSON Department of Applied Mechanics Chalmers University of Technology ABSTRACT This thesis is concerned with methods to extract material properties of thin adhesive layers loaded in peel and in mixed mode. The first part of the thesis is devoted to an experimental method to determine the complete stress-elongation relation (or cohesive law) for an adhesive layer loaded in peel using the DCB-specimen.

  3. 3. Implementation of a flexible fiber model in a general purpose CFD code

    University dissertation from Chalmers University of Technology

    Author : Jelena Andric; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastkroppsmekanik; Solid mechanics; Strömningsmekanik; Fluid mechanics; flexible fiber; LPT; CFD; OpenFOAM;

    Abstract : This work is related to the process of making pulp mats for use in hygienic products. One part of that process is the transportation of flexible cellulose fibers suspended in flowing air. The fibers should be evenly distributed on the substrate, and it is thus of high importance to avoid the formation of fiber flocks during the transportation. READ MORE

    Abstract : Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. READ MORE

  5. 5. Prediction of springback in sheet metal forming: with emphasis on material modeling

    University dissertation from Chalmers University of Technology

    Author : Per-Anders Eggertsen; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastkroppsmekanik; Solid mechanics; Hardening law; Springback; Bauschinger effect; Yield surface; Elastic degradation; Simulation;

    Abstract : The prediction of springback is probably the area in sheet metal forming simulation, where the least success has been achieved in terms solution accuracy. The springback is caused by the release of the residual stresses in the work piece after the forming stage. READ MORE
