Demonstration of Implicit & Explicit Analysis in Finite Element Analysis. LS-Dyna & ANSYS can be used for either Implicit or Explicit Analysis.
IMPLICIT ANALYSIS: No effect of mass (inertia) or of damping,
Static analysis is done using an implicit solver,
solution of each step requires iterative solutions to establish equilibrium within a certain tolerance, Time steps are generally larger than explicit time steps, Requires a numerical solver to invert the stiffness matrix once or even several times over the course of a load/time step, which is expensive for large models.
EXPLICIT ANALYSIS: Mass/inertia and damping are included,
Dynamic analysis can be done via the explicit solver,
No iteration is required as the nodal accelerations are solved directly, No inherent limit on the size of the time step, Time step must be less than the Courrant time step, Dose not require matrix inversion, Handles contact and material nonlinearities with relative ease, Once accelerations are known at time n, velocities are calculated at time n+1/2, and displacements at time n+1, from displacements comes strain, from strain comes stress & the cycle is repeated.
The intent of this channel is to provide the complete solution for engineering problems related to Structural, Thermal & Fluid flow.
You can get trained on FEA applications like ANSYS, Hypermesh, ANSA, LS-Dyna & Design applications like Creo Parametric, Solid works, Auto CADD.
We do handle Industrial projects, IEEE Projects, Students Projects. Research projects

#ANSYS
You can now get trained on the tools and technologies by sitting at your place. We provide both classroom and online training for students and professionals who can not travel can make best use of this online face to face training. The trainer are corporate professionals, and there is no compromise on the quality we deliver.
