Fulcrum’s analysis team focuses on developing lightweight yet robust solutions for the modern warfighter. Fulcrum’s team uses the latest Finite Element Analysis (FEA) software to quickly iterate and optimize solutions. Backing up the software is a deep understanding of the fundamentals of structural design and analysis, allowing for a broader and more effective solution set. The analysis team uses a combination of static linear/non-linear analysis, crack growth simulation, and a whole suite of dynamic analyses to fully federate systems and system modifications on any platform. The team has successfully completed many full AWR and STC approvals including weapons systems, internal and external aircraft modifications, and pressure bulkhead modifications. The Fulcrum analysis team’s scope and depth of analysis has shown to produce the lightest solutions while maintaining full usability and robustness on the battlefield.

FEMAP+NASTRAN

Fulcrum employs world class stress analysts which are efficient in multiple suites of FEA solvers.
FEMAP+NASTRAN allows the analysts to solve statically indeterminate structures using the following NASTRAN solutions:
- Linear static
- Eigenvalue buckling/stability
- Normal Modes
- Frequency/Transient Response
- Nonlinear static (material and geometric nonlinear)
- Multistep nonlinear static and dynamics
NASTRAN superelement capabilities allows FEA models to be incorporated with attachment structure to better predict the interaction with existing structure. Fulcrum analysts have experience incorporating OEM airframe FEA models into new designs.

Dynamic Response
Structural Dynamics Analysis

Rotorcraft structure typically experiences high vibration levels so accurately predicting the dynamic response of the structure is critical in determining the fatigue life and performance.
Using NASTRAN normal modes and forced response analysis, Fulcrum is able to determine detailed mode shape and frequency predictions, as well as iterate through various store mass configurations to predict test results and identify critical store configurations.
Fulcrum has extensive experience in structural dynamics and has a proven track record of accurately predicting structural response within 5%.
