    AI Summary
    • Parth Akbari, Structural Engineer at MIDAS IT Australia, introduces material non-linear analysis in MIDAS CIVIL NX, covering the difference between linear and non-linear structural response and how to model behaviour beyond the elastic limit.
    • The session walks through a combined linear and non-linear buckling analysis workflow — from geometric imperfections and plastic material assignment through to non-linear parameter setup and result interpretation on a box girder model.

    Description

    In this session, Parth Akbari, Structural Engineer at MIDAS IT Australia, introduces material non-linear analysis in MIDAS CIVIL NX — explaining the difference between linear and non-linear structural response, and when engineers need to move beyond elastic analysis.

    Parth walks through the full linear and non-linear buckling analysis workflow: running a linear buckling analysis, updating the geometry with imperfections, assigning plastic material properties, enabling combined non-linear analysis, and extracting the load factor–displacement curve. The session then moves into MIDAS CIVIL NX, demonstrating mode shape review, non-linear analysis control settings, and deformation and stress results on a box girder model.

    This is the fourth and final session in MIDAS IT Australia's free weekly CIVIL NX training series, designed to give engineers across Australia and New Zealand a fast, practical look at core workflows.

    Key Points

    Difference between linear and non-linear structural response, and when non-linear analysis is needed

    Workflow: linear buckling analysis → geometry update with imperfections → plastic material assignment → combined non-linear analysis → load factor–displacement curve
