Abstract: In the present work, inelastic dynamic behavior of a pressurized stainless steel elbow is studied under harmonic base excitation with the emphasis on strain accumulation known as ratcheting. Initially, sine sweep test is ...

Abstract: In pressurized piping systems, strain accumulation may take place due to cyclic loading during a seismic event. This incremental plastic deformation called ratcheting may lead to failure of the piping systems. There is no ...

Abstract: Rational seismic design procedures necessitate comprehensive evaluation of nuclear piping systems under large amplitude seismic loads. This comprehensive assessment requires accurate prediction of inelastic response of ...
