Evaluation of locking mitigation techniques and development of locking-free ANCF shell elements for nearly incompressible materials based on the Yeoh model

Key Points

• The locking-free ANCF shell elements enhance modeling for nearly incompressible materials, improving accuracy and stability.
• Key evidence shows significant reduction in locking effects, marked by improved performance metrics in simulations.
• Assessment of locking mitigation techniques demonstrates their effectiveness in enhancing material behavior predictions.
• This work may enable broader applications of finite element methods for complex material structures; further tests are needed.
