| Abstract: | To understand and improve the crashworthiness of flexible containers,the dynamic behaviors of the container under impact loading were numerically simulated.The water movement and sloshing in the container were modeled by using the ALE method.The interaction between the container and fluid was studied by applying the penalty method.The model and approaches were validated by comparing numerical results with experimental data.Based on the above investigation,numerical simulation was performed to explore the in... |
