Stress Analysis

NTS can subject your structure to the loads that it will experience in testing before it ever gets to the test stand, thereby identifying potential design problems and providing the critical insight needed to address them in advance so that you can breeze through the formal testing process.  Our stress analysis capabilities cover a wide range of functional requirements:

• FEA (finite element analysis) using ANSYS and NASTRAN to make sure that stress levels do not exceed material allowables
• Shock analysis to meet MIL-STD-901
• Drop test analysis
• Fracture mechanics to predict crack growth, as required by NASA
• Material selection for strength, corrosion resistance, fatigue resistance, and weight
• Impact analysis using LSDYNA for bird strike, tire fragments, and containment of high energy rotating parts
• Thermal growth and thermal stress prediction
• Failure analysis and recommendations for design optimization
