The second workshop describes water movement in a pipe after the bullet’s passage. Workshop 2: Bullet Movement through Water Pipe in Abaqus An Elastic model is used for the windshield, while the Us-Up model is used for the bird. We converted the C3D8R to PC3D and made other changes to facilitate interaction. The first method involves using ABAQUS CAE, which can be a bit challenging, while the second method involves modifying the input file. There are two ways to implement the SPH procedure in ABAQUS. The SPH formulation is employed to model the bird’s behavior in this particular example. During the analysis, the bird collides with the windshield. This workshop provides a detailed guide for simulating a bird strike in ABAQUS. Workshop 1: Bird Strike Simulation in Abaqus You can learn how to use this method by practical examples in this package some of them are Projectile impact simulation on a cementitious material, TNT explosion simulation inside a rock with the SPH method, Bullet Movement through Water Pipe in Abaqus. Consequently, element deletion and element conversion can’t use together. Converting to SPH particles offers an improvement over the element deletion method because the generated particles can provide resistance to deformation beyond finite element distortion levels. Traditionally, in such cases, deletion of the soon-to-be distorted Lagrangian elements would be the only choice to allow the analysis to continue. The conversion technique of generating particles per parent element is intended to be used when the original finite element mesh deformations are significant and elements may distort.
These two conversion techniques make use to turn Lagrangian elements to SPH particles. Particles can be generated per parent element, or particles can be generated based on a uniform background grid. It can be used in combination with other Abaqus features, such as finite element analysis, to model coupled fluid-structure systems. Abaqus’ implementation of SPH includes a wide range of capabilities, such as adaptive smoothing lengths, particle splitting and merging, and boundary handling techniques. The method is particularly useful for problems with large deformations, fragmentation, and free surface effects.
It is a meshless approach that uses a set of particles to discretize the fluid domain, allowing for efficient and accurate simulation of complex flows.
