"解决abaqus中的收敛问题：非线性FEA培训教材与实践指导"。

The Abaqus Convergence Training Manual, titled "Obtaining a Converged Solution with Abaqus," provides a comprehensive overview of nonlineaor for those using Abaqus for nonlinear finite element analysis (FEA). The training course covers the difficulties in obtaining a converged solution with Abaqus and provides practical workshops to help participants understand the complexities of nonlinear FEA. The manual is structured into several sections, with Day 1 focusing on the fundamental aspects of nonlinear FEA. The lectures on Day 1 include an introduction to nonlinear FEA, nonlinear FEA with Abaqus/Standard, and the solution of unstable problems. Workshop sessions are also included on Day 1, which involve analyzing a nonlinear spring and a reinforced plate under compressive loads. These workshops allow participants to apply the knowledge gained from the lectures to practical engineering problems. One of the key focuses of the training is on understanding why Abaqus sometimes fails to find a converged solution. The manual delves into convergence problems, particularly in contact simulations, and provides workshops on crimp forming analysis, contact beam lift-off, and contact stabilization. These workshops aim to give participants hands-on experience in dealing with convergence issues in complex engineering problems. Overall, the Abaqus Convergence Training Manual is designed to equip engineers and analysts with the knowledge and skills to effectively handle convergence problems in nonlinear FEA using Abaqus. The material is presented in a clear and organized manner, with a balance of theoretical lectures and practical workshops to ensure a comprehensive understanding of the topic. This manual serves as a valuable resource for professionals working in the field of nonlinear FEA and using Abaqus as their simulation tool.
