Durability Analysis

Fatigue Life Based on Constant Amplitude/Rain-Flow Counted Spectrum
Fatigue analysis is generally sufficient for parts with relatively long lives (>10,000 CYCLES) that are not Principal Structural Elements (PSE). For these analyses, we can determine material medication factors and geometrical stress concentrations. This can be done through classical methods where available or with a detailed Finite Element Model when necessary.

Damage Tolerance Analysis

Prescribing Inspection Intervals Using Commercial Software

For parts that are PSE or have relatively short fatigue life (<10,000 CYCLES), we typically complete a more thorough crack growth analysis using the NASGRO software. Our engineers generally use either public domain beta factors or Da/DN curves, but we have the capability to use our client’s information as well. Apart from this, we have experience with providing inputs for determining inspection intervals depending on inspectability for single and multiple initiation sites.

Structural Analysis

Fuselage, Wing, Landing Gear, and Nacelle Components

Our team has experience with multiple aircraft platforms in development, repair, and modification roles. With our extensive aircraft expertise, we are capable of delivering innovative solutions to both simple and complex problems.

Finite Element Analysis

Linear, Non-Linear, Contact, Natural Frequency, Windmilling, and Buckling

We currently use the entire suite of MSC-One products. Our engineers also have experience with other applications such as:

• MSC-Apex – Detailed sub-component level models
• MSC-Patran/Nastran – Airframe level loads models, global/local models using glue contact, DMIG creation, loads extraction, non-linear, modal, and transient solutions
• Femap – Airframe level loads models, subcomponent level models, detailed mesh models
• LS-PrePost/LS-DYNA – Subcomponent level models for linear and non-linear analysis
