Implicit and explicit analysis

#implicit analysis  #types of analysis #explicit analysis

As we all know that there are several types of analysis we do in structures but broadly , We can classify the types of analysis into two categories implicit & explicit. many young engineers have confusion how they are different in this this blog we know the major difference between them.

We often encounter the terms Static analysis and dynamic analysis 

Static analysis - Analysis in Equilibrium, No inertial effect

Dynamic Analysis- Analysis involves speed and acceleration, Possesses inertial effect.

In static analysis, there is no effect of mass (inertia) or of damping. In dynamic analysis, nodal forces associated with mass/inertia and damping are included.

Implicit Analysis _ implicit analysis has several characteristics that are necessary for this class of analysis

Given below are some examples of analysis cable to solve by implicit solvers.

1. Equilibrium Problem

2. Solver will converge at each time increment

3. Time independent

Explicit  Analysis _ Explicit analysis are dynamic in nature and time dependent

Given below are some examples of analysis cable to solve by implicit solvers.

1. Non equilibrium Problem 

2. Solver will not converge at each time increment

3. Time dependent
