Finite Element Analysis (FEA)
We currently use Finite Element Analysis (FEA) to evaluate strength and stability of a large variety of naval and marine structures. We provide consulting services for the design of the entire ship hull girder or just local portions of it.
We have developed a significant experience in performing strength and stability analyses of submarine pressure hulls in accordance with the main Classification Societies (ABS, DNV, RINA).
Our areas of expertise include:
- Dynamic characterization of the structure through accurate modal and harmonic analyses.
- Prediction of all forms of frequency response function of the supporting structure in the low-medium frequency range, namely dynamic stiffness, mobility, impedance, inertance, etc.
- Prediction validation through modal testing techniques.
- High and low cycle fatigue analysis.
- Evaluation of fatigue damage and residual fatigue life due to random vibration.
- We can calculate fatigue crack initiation life and perform subsequent fracture mechanics analysis to determine crack progression.
- Response spectrum analysis as an alternative way of evaluating shock strength and maximum deflections of complex structures subject to shock load or earthquake acceleration.
