We conduct aircraft stress analysis using a combination of classical methods and numerical simulation tools to evaluate and optimize the sizing of structural components. To build Finite Element Models (FEM), TLG uses the latest industry-leading meshing tools. TLG can run a comprehensive range of simulations, including linear static, modal, buckling, frequency response, thermal, implicit, and explicit nonlinear.
TLG employs large computing clusters to support time-intensive simulations and analysis, with the added capability of supporting multiple parallel solutions to alleviate bottlenecks and maintain program schedules.

More Than a FEM
Ensuring aircraft components meet critical requirements demands more than just a FEM analysis; evaluating the primary structure may also involve Fatigue and Damage Tolerance (F&DT) assessments. Addressing criteria such as Failsafe or Safe-life early in the development cycle can significantly alter the test and certification approach. TLG’s engineers are experienced with F&DT analysis tools and continued airworthiness documents that Category 23 and 25 aircraft require.
TLG also supports aerospace-related tooling programs, including thermal and stress analysis of high-pressure Resin Transfer Molds (TRM), transitional autoclave and oven thermal cycle analysis, and specialized large-scale aircraft shipping fixtures. TLG understands that many of these tools do not require the fidelity of certified airframe components and that many tasks must be completed within tight deadlines.
Also, our internally developed stress analysis templates can be used to generate certification-level reports. TLG can provide support for test instrumentation definition and test plan creation and review when validation of the structure is required.
