Explicit dynamics accuracy is, in part, a function of element size. Generally, the smaller the elements, the more accurate the results — but this requires longer compute times. Ansys HPC techniques allow you to improve accuracy as well as to examine multiple designs in a given time.

In explicit dynamic analysis, nodal accelerations are solved directly (not iteratively) as the inverse of the diagonal mass matrix times the net nodal force vector where net nodal force includes contributions from exterior sources (body forces, applied pressure, contact, etc.), element stress, damping, bulk viscosity, and hourglass control.

09.07.2019 · ANSYS Explicit Dynamics analysis software provides simulation technology to help simulate structural performance long before manufacture. ANSYS explicit dynamics analysis software solutions are capable of solving short-duration, large-strain, large-deformation, fracture, complete material failure, and structural problems with complex contact interactions.

The Ansys explicit dynamics suite enables you to capture the physics of short- duration events for products that undergo highly nonlinear, transient dynamic.

06.10.2016 · Ansys | Explicit Dynamics | How To Create Simple Explicit Dynamics Analysis

An explicit, dynamic analysis is computationally efficient for the analysis of large models with relatively short dynamic response times and for the analysis of extremely discontinuous events or processes. This type of analysis allows for the definition of very general contact conditions and uses a consistent, large-deformation theory.

29.11.2020 · Explicit analysis offers a faster solution in events where there is a dynamic equilibrium or otherwise: Sum of all forces = mass x acceleration The explicit method should be used when the strain rates/velocity is over 10 units/second or 10 m/s respectively.

The Ansys explicit dynamics suite enables you to capture the physics of short-duration events for products that undergo highly nonlinear, transient dynamic forces. Our specialized, accurate and easy-to-use tools have been designed to maximize user productivity. With Ansys, you can gain insight into how a structure responds when

Specialised design problems involving short-duration high-pressure loadings generally require the use of explicit dynamics methods to obtain a good answer within reasonable time scales.

The explicit dynamics procedure performs a large number of small time increments efficiently. An explicit central-difference time integration rule is used; each increment is relatively inexpensive (compared to the direct-integration dynamic analysis procedure available in Abaqus/Standard) because there is no solution for a set of simultaneous equations.

The explicit integration rule is quite simple but by itself does not provide the computational efficiency associated with the explicit dynamics procedure. The key to the computational efficiency of the explicit procedure is the use of diagonal element mass matrices because the inversion of the mass matrix that is used in the computation for the ...

Jul 09, 2019 · “Implicit” and “Explicit” refer to two types of time integration methods used to perform dynamic simulations. Explicit time integration is more accurate and efficient for simulations involving – Shock wave propagation – Large deformations and strains – Non-linear material behaviour – Complex contact – Fragmentation – Non-linear buckling. Typical applications are drop tests ...
