Abstract:
This work addresses the study on contact modelling in isogeometric analysis. Research papers including vehicle crashworthiness and occupant protection, on contact modelling in isogeometric analysis, contact searching algorithm is described. CAD modelling of front vehicle bumper and rigid pole is done after that model is discretized using software. Isogeometric analysis has been described as a tool for geometric modelling and surface discretization. MATLAB software package is used for generating mesh, applying the boundary condition, solving the system of equations for stress and displacements and visualising the solution results. For comparison of the results between FEM and Isogeometric analysis an ABAQUS/CAE simulation is used.
