Composite Laminates in Tdyn RamSeries!"},"content":{"rendered":"\n

We are thrilled to announce a powerful new capability in Tdyn RamSeries<\/a><\/strong>: a dedicated module for Fatigue Damage Assessment <\/a>(FDA) in composite materials<\/strong>!<\/p>\n\n\n\n

Understanding and predicting fatigue is critical for ensuring the safety and durability of composite structures in high-performance sectors like marine, aerospace, and renewable energy. With our latest implementation, engineers can now accurately predict the fatigue life of complex composite laminates, preventing premature failure and optimizing designs for longevity.<\/p>\n\n\n\n

What’s New?<\/h2>\n\n\n\n

Our new FDA tool is built on a robust methodology that calculates fatigue damage based on the Palmgren-Miner linear damage rule<\/strong>. <\/p>\n\n\n\n

This allows for the prediction of failure nucleation once the fatigue damage reaches a critical value (d=1.0).<\/p>\n\n\n\n
