What is Ansys?
Ansys structural analysis software enables you to solve complex structural
engineering problems and make better, faster design decisions. With the
finite element analysis (FEA) solvers available in the suit you can customize
and automate solutions for your structural mechanics problems and
parameterize them to analyze multiple design scenarios.
FEA – Finite Element Analysis

How does finite element analysis works?
 FEA uses a complex system of points called nodes which make a grid called as
mesh.
 This mesh is programmed to contain the material and structural properties
which define how the structure will react to certain loading conditions.
 Regions which will receives large amount of stress usually have a higher node
density than those which experiences little or no stress.

Types of stimulations Ansys software can
perform
 Linear Static analysis
 Non- linear analysis
 Dynamic analysis
 Buckling analysis
 Thermal analysis
 Fatigue analysis
 Optimization
 CFD analysis
 Crash analysis
 NVH analysis

Linear Static Analysis
 This analysis also called as static structural analysis
 It determine deflections, stresses, factor of safety etc. based
on standard strength of material concepts under static
loading.

Non- Linear Analysis
 A nonlinear analysis is an analysis where a nonlinear
relation holds between applied forces and displacements.
 A nonlinear static analysis is required for any static
application in which the stiffness of the entire structure
changes during the loading scenario.

Dynamic Analysis
 Dynamic analysis, also known as dynamic program analysis, is the
evaluation of a program or technology using real-time data.
 If your application model involves loads that are changing rapidly,
significant accelerating or decelerating motions will be developed, thus
inertial forces will be present and a dynamic analysis is required to
capture their effects.

Buckling Analysis
 Buckling Analysis is an FEA routine that can solve all the difficult buckling
problems that cannot be solved by hand calculations.
 Buckling is the failure mode of a structural member experiencing high
compressive stresses that cause a sudden sideways deflection.
 It determines failure load or safety factor for buckling and it’s buckling mode
shapes.

Thermal Analysis
 Thermal analysis is a general term
defining a technique used to analyze
the time and temperature at which
physical changes occur when a
substance is heated or cooled.
 It studies the effect the change in
temperature might have on material
properties. ... This helps the company
in developing a water boiler that is
more robust and can resist high
temperature and heat.

Fatigue Analysis
 Fatigue Analysis is the structural analysis
of failure tendency of systems when
subjected to cyclical loads.
 Fatigue analysis establishes whether your
model is susceptible to fatigue damage
when subjected to a varying load.

Optimization
 finite element computational
method to decide what the optimal
shape is for a given design space
and set of loads and constraints.
 A shortened design process:
Topology optimization can
drastically reduce product
development timelines which
translates to reduced costs.

CFD Analysis
 CFD stands for Computational fluid
Dynamics
 CFD modeling looks to solve equations
describing the fluid flow and heat transfer
from the growth and spread of fire.
 CFD provides information on important
flow characteristics such as pressure loss,
flow distribution, and mixing rates.

Crash Analysis
 The purpose of a crash analysis is to see
how the car will behave in a frontal or
sideways collision.
 The crash analysis simulation and results
can be used to assess both the
crashworthiness of current frame and to
investigate ways to improve the design.
 Crash analysis is performed on car body
designs for ensuring safety of passengers
in accidents.

NVH Analysis
 Noise, vibration, and harshness (NVH), also known as noise and vibration,
is the study and modification of the noise and vibration characteristics of
vehicles, particularly cars and trucks.
 Every object that moves or is put into motion can cause potentially critical
noise and vibration problems. In combination with motor vehicles, NVH is
an important criterion for driving comfort. This includes the sum of all
audible and perceptible vibrations that affect this comfort.
