Few months back I blogged about
difference between explicit dynamic and implicit analysis. Concisely
summarizing, an implicit analysis is the one which is independent of time and
explicit is the one which is of a short duration and time dependent. In
this post, I would be going into details regarding an Implicit Finite Element
Analysis. Newton-Raphson (NR) method is the commonly used method for most of
the implicit FE solvers. In simple numerical terms, the N-R method is used for
finding successively better approximations. Figure 1 shows the general
iterative process for an implicit analysis. Click here to
read more about N-R method.
