We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello, 

I would like to know if I set up the shell wrapped beam unit, will the reinforcement still have the effect of bond slip? - Could you elaborate a little bit more about it? 

I will try the DEM below, will there be a significant difference between it and SPH? - DEM is implemented for calculations involving discrete spherical elements. It supports only spherical particles, each consisting of a single node with its mass, mass moment of inertia, and radius defined by the input. Initial coordinates and velocities are specified using the nodal data. While the SPH is a continous method developed to avoid the limitations of mesh tangling encountered in extreme deformation problems with the finite element method.

Please look at the examples: https://www.dynaexamples.com/sph and DEM: https://www.dynaexamples.com/dem
