This topic is too broad; it’s difficult to cover all the specific details and case studies in detail here. However, I can provide a general overview and direction: - **Thermomechanical coupling analysis**: - **Basic steps**: include modeling, definition of material properties, meshing, boundary condition and loading setup, solution calculation, and post-processing. - **Case **: Analyze the strength of the joint between the cylinder shell and the head, and assess its stress level ； Or conduct flow field and thermal stress field analysis on the LNG cryogenic tank. - **Stability analysis**: - **Basic content**: Stress analysis under loads such as loading/unloading, motion, and earthquakes, with the use of ANSYS for Linear Buckling analysis. - **Case **: Analyze the local instability of pressure vessels, as well as the nonlinear buckling of the shell top. - **Nonlinear analysis**: - **Method**: ANSYS Workbench is used for the nonlinear analysis of the structure. - **Case study **: The specific analysis cases will depend on particular design requirements and issues. - **China and USA Code for Analysis and Design of Pressure Vessels**: - **Content**: Covers failure modes such as plastic collapse, local failure, buckling failure, fatigue, ratcheting effect, and creep-fatigue, as well as the assessment criteria specified in the Chinese and American codes. - **Practical cases**: – Include shock and seismic analysis of large-scale equipment under wind and seismic loads, elastoplastic ratchet assessment, fatigue analysis based on structural stress, as well as local structural analysis of high-pressure vessels. - **Guidance for Designers’ Exams**: – Covers the application of the JB4732 design standard, common mistakes in stress analysis, the preparation of analysis reports, as well as skills for design reviews and SAD analysis defense. Since the use of ANYS relies heavily on software operation skills and engineering background knowledge, if you need to learn it or study it in depth, it is recommended to consult ANYS’s official documentation, tutorial videos, as well as relevant books on engineering analysis. At the same time, participating in relevant training or online courses is also a good option. .
