  1. 1. Spot welded ENF-Specimen

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Antonio Rafael García Gil; Oualid El Mernissi; [2014]
    Keywords : spot; welded; reinforced; ENF; specimen; adhesive; ABB; Robotics; steel; sheets;

    Abstract : The behaviour of spot welded joints is to be studied in shear mode by using the end notched flexure (ENF) specimen. The specimen counts on several spot welds spaced with the same gap along the entire length except for the notch. READ MORE

  3. 2. Stability of End Notched Flexure Specimen

    University essay from Institutionen för teknik och samhälle

    Author : Arun Gojuri; [2010]
    Keywords : Energy release rate; Finite element method; ENF-specimen; Delamination; Composite material; isotropic orthotropic; controlled displacement;

    Abstract : This paper deals with two-dimensional Finite Element Analysis of the End Notched Flexure (ENF) specimen. The specimen is known to be unstable if the crack length is shorter than some critical crack length acr. READ MORE

  4. 3. System for measurement of cohesive laws

    University essay from Institutionen för teknik och samhälle

    Author : Tomas Walander; [2009]
    Keywords : End Notched Flexure; J-integral; Cohesive law; Finite element method; Energy release rate;

    Abstract : In this thesis an experimental method to calculate cohesive characteristics for an adhesive layer in a End Notched Flexure (ENF) specimen is presented and evaluated. The method is based on the path independent J-integral where the energy release rate (ERR) for the adhesive is derived as a function of the applied forces and the rotational displacements at the loading point and at the supports of the specimen.

  5. 4. Evaluation of an Interphase Element using Explicit Finite Element Analysis

    University essay from Institutionen för teknik och samhälle

    Author : Daniel Svensson; Tomas Walander; [2008]
    Keywords : Explicit finite element analysis; double cantilever beam; end notched flexure; critical time step;

    Abstract : A research group at University of Skövde has developed an interphase element for implementation in the commercial FE-software Abaqus. The element is using the Tvergaard & Hutchinson cohesive law and is implemented in Abaqus Explicit version 6.7 using the VUEL subroutine. READ MORE
