  1. 6. A finite element study of shell and solid element performance in crash-box simulations

    University essay from Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Author : Mahdi Bari; [2015]
    Keywords : Crash analysis; solid elements; shell elements; LS-Dyna; Impetus AFEA; Hypermesh;

    Abstract : This thesis comprehends a series of nonlinear numerical studies with the finite element software's LS-Dyna and Impetus AFEA. The main focus lies on a comparative crash analysis of an aluminium beam profile which the company Sapa technology has used during their crash analysis. READ MORE

  3. 7. Simulations of the response of concrete structures subjected to air blasts

    University essay from Lunds universitet/Byggnadsmekanik

    Author : Peter Svantesson; [2013]
    Keywords : Load blast; reinforced concrete; structural response; finite element analysis; LS-DYNA; LOAD BLAST ENHANCED; shell element; Technology and Engineering;

    Abstract : The response of concrete structures subjected to blast load can be studied numerically using commercial finite element programs. The complexity of reinforced concrete makes modeling and simulation of large structures time and computer power consuming. READ MORE

  4. 8. Parametric model for structural stability computation of chassis in tipper trailers.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Maria Lagergren; [2011]
    Keywords : ;

    Abstract : When a tipper trailer empties the load it carries, a torque occurs if the trailer stands on uneven ground. To withstand this torque, and prevent the trailer to roll over, the chassis‟ torsional stiffness must be high enough. The stiffness is highly dependent of the geometry of the chassis structure.

  5. 9. Finite Element Modeling of Rubber Bushing for Crash Simulation - Experimental Tests and Validation

    University essay from Lunds universitet/Byggnadsmekanik

    Author : Oscar Jesus Centeno Gil; [2009]
    Keywords : Technology and Engineering;

    Abstract : Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. READ MORE

  6. 10. A New H-Adaptive Method for Shell Elements in LS-Dyna

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Byggnadsmekanik

    Author : Ivan Oskarsson; [2006]
    Keywords : Technology and Engineering;

    Abstract : This thesis describes the development of a new h-adaptive method for shell elements in the explicit FE-code LS-DYNA. Adaptivity is used to obtain accurate results for large deformation analyses to a low computational effort. However, the present adaptive method available in LS-DYNA is based on a geometrical simplification. READ MORE
