Stress Analysis & Weight Optimization

Abbott Aerospace has extensive experience of stress analysis and weight reduction across multiple military and civil, manned and unmanned aircraft projects..

Abbott Aerospace has performed initial sizing for multiple aircraft in the early layout stage, taking preliminary loads and using classic hand methods for critical element initial sizing.

This initial sizing estimate is used for the first aircraft finite element model. We have produce aircraft level meshes for many complete aircraft and applied loads either via RBE3 elements or directly on the mesh nodes.

We have worked through multiple iterations of complete aircraft finite element models to produce internal loads and stress/strains. We have experience of producing very high quality meshes with ordered grouping that allows quick and clear post processing and sorting of output data.

We are at ease with linear static, non linear static, linear buckling and non linear buckling and transient analysis. We provide a least weight solution with complete confidence.

We have experience of modelling composite structure with ‘thick’ laminate element properties or with solid elements sandwiched with thin laminate elements

All of the non linear analysis work is duplicated with a hand analysis to provide correlation and comparison. Where available, we will use empirical data to further build confidence.

We have experience of modelling composite structure with ‘thick’ laminate element properties or with solid elements sandwiched with thin laminate shell elements.

All of the non linear analysis work is duplicated with a hand analysis to provide correlation and comparison. Where available, we will use empirical data to further build confidence.

We back up all of our finite element analysis with hand calculations of critical joints and critical features and sections.

Plastic bending, fasteners, lugs, columns, panels and flanges are all individually considered outside of the finite element model using our own set of analysis spreadsheets.

Our stress analysis spreadsheet methods have been downloaded hundreds of thousands of times are used by thousands of engineers from Singapore to Seattle.
