Product Overview:

This video provides a comprehensive, step-by-step explanation of the explosive welding process between two pipes using Abaqus. The inner pipe, known as the flyer pipe, is composed of titanium, while the outer pipe, referred to as the base pipe, is made of steel. Both pipes are modeled as axisymmetric components, along with TNT, which is also treated as an axisymmetric part. The behavior of TNT is modeled using the Jones-Wilkens-Lee (JWL) equation of state.

During the simulation, the titanium pipe acts as the flyer, moving towards the steel pipe. The explosive force from the TNT generates significant pressure on the flyer pipe, resulting in a weld joint formed at the interface of the two pipes. The quality of the mesh plays a crucial role in the accuracy of the results; therefore, increasing the number of elements is essential for improved outcomes.
