  • A cover-based contact detection approach for irregular convex polygons in discontinuous deformation analysis 
    Zhuang, Xioaying; Zheng, Fei; Zheng, Hong; Jiao, Yu-Yong; Rabczuk, Timon; Wriggers, Peter (New York, NY [u.a.] : Wiley, 2021)
    Irregular polygon shapes (eg, with small edges or small angles) are usually encountered in the contact simulation of discrete block systems. Treatment of irregular polygons in contact detection process has critical effects ...
  • Applying membrane mode enhanced cohesive zone elements on tailored forming components 
    Töller, Felix; Löhnert, Stefan; Wriggers, Peter (Basel : MDPI AG, 2020)
    Forming of hybrid bulk metal components might include severe membrane mode deformation of the joining zone. This effect is not reflected by common Traction Separation Laws used within Cohesive Zone Elements that are usually ...
  • Blast protection with fluids 
    Rigoulet, Tatiana (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2024)
    Bei der Detonation einer Sprengladung unter dem Boden eines Fahrzeugs, z. B. einer vergrabenen Mine oder eines improvisierten Sprengkörpers, treten zwei Haupteffekte auf: die Verformung oder Zerstörung des Fahrzeugbodens ...
  • A contact detection algorithm for superellipsoids based on the common-normal concept 
    Wellmann, Christian; Lillie, Claudia; Wriggers, Peter (Bingley : Emerald Group Publishing Ltd., 2008)
    Purpose - The paper aims to introduce an efficient contact detection algorithm for smooth convex particles. Design/methodology/approach - The contact points of adjacent particles are defined according to the common-normal ...
  • Elastic-plastic analysis of metallic shells at finite strains 
    Campello, Eduardo Moraes Barreto; De Mattos Pimenta, Paulo; Wriggers, Peter (Ouro Preto : REM, 2007)
    The geometrically-exact finite-strain variable-thickness shell model of [1] is reviewed in this paper and extended to the case of metallic elastoplastic shells. Isotropic elasticity and von Mises yield criterion with ...
  • Entwicklung einer netzfreien Simulationsmethode auf Basis der flexiblen Elemente 
    Bode, Tobias (Hannover : Gottfried Wilhelm Leibniz Universität, 2017)
    Die Finite Element Methode (FEM) hat sich im Ingenieurwesen aufgrund seiner stabilen und numerisch genauen Approximation der Lösung von partiellen Differenzialgleichungen als Simulationswerkzeug bewährt. Aufgrund der ...
  • Finite element formulations for large strain anisotropic material with inextensible fibers 
    Wriggers, Peter; Schröder, J.; Auricchio, F. (Heidelberg : Springer Verlag, 2016)
    Anisotropic material with inextensible fibers introduce constraints in the mathematical formulations. This is always the case when fibers with high stiffness in a certain direction are present and a relatively weak matrix ...
  • High performance computing for modelling of stereolithography process 
    Kumar, Sandeep (Hannover : Institut für Kontinuumsmechanik, Leibniz Universität Hannover, 2022)
    In this dissertation, a state-of-the-art 3D computational model has been developed for Stereolithography process to investigate the evolution of properties in a multi-physics framework using Stabilized Optimal Transportation ...
  • Non-local ductile damage formulations for sheet bulk metal forming 
    Beese, Steffen; Loehnert, Stefan; Wriggers, Peter (Bristol : Institute of Physics Publishing, 2016)
    A ductile damage model for sheet bulk metal forming processes and its efficient and accurate treatment in the context of the Finite Element Method is presented. The damage is introduced as a non-local field to overcome ...
  • Numerical simulations of delamination in fibre reinforced plastic shell structures using XFEM 
    Yazdani, Saleh (Hannover : Institut für Kontinuumsmechanik, Leibniz Universität Hannover, 2016)
    [no abstract]
  • Particle-based Simulation of the Selective Laser Melting Process 
    Fürstenau, Jan-Philipp (Hannover : Institut für Kontinuumsmechanik, 2020)
    Additive manufacturing (AM) is becoming increasingly popular on an industrial level, as it allows for components to be designed much more freely than with conventional methods. For example, additive manufacturing can be ...
  • Simulation of the Particle Distribution and Resulting Laser Processing of Selective Laser Melting Processes 
    Bode, Tobias (Hannover : Gottfried Wilhelm Leibniz Universität, 2017)
    Selective Laser Melting (SLM) is a 3D printing technology which is suited for additively manufacturing of metals and polymers. The main barriers of this process are the lack of reproducibility and the control of the influence ...
  • Thermo-mechanical modeling for selective laser melting 
    Wessels, Henning (Hannover : Institut für Kontinuumsmechanik, Leibniz Universität Hannover, 2019)
    Selective Laser Melting (SLM) is an Additive Manufacturing (AM) process where a powder bed is locally melted with a laser. Layer by layer, complex three dimensional geometries including overhangs can be produced. Up to ...
