HMA Materials Handling has been carrying out Finite Element Analysis on its own designs and for clients for many years.

We also do many certifications of small items such as lifting lugs, lifting beams, excavator and crane attachments, boom pivot points and similar.

We use strand7, an Australian designed FEA package. This package provides excellent graphics for the presentation of results. Of course, FEA is only a solver of mathematical equations, and the old adage “garbage in – garbage out” truly applies in this field. It is the ability and experience of the designer-operator which produces the results. Selections of boundary conditions, static and dynamic factors on forces, derivation of actual loads to be applied, interpretation of stress levels, and the way features are modelled will be key factors in a successful design.
