�Vaftsy can provide design support to your business.
�We can engage in your design process, right from
Product conception to Product delivery
�We shall add value to your business, in the
�We shall add value to your business, in the
following areas
�Increased Reliability of Products
�Anticipation of Potential Problem Areas
�Quicker Delivery of Design
�Flexibility for Design Changes
FEA Introduction
�FEA is methodology for Virtual analysis of
Engineering Components
�FEA is aimed at simulating working conditions of
Products, and analyzing the performance of the
product.
Products, and analyzing the performance of the
product.
�FEA enables designer’s to anticipate problems with
components, and hence deliver better designs
CASE Study
�FEA was done for a tooling component being
manufactured at one of our clients
�We performed an analysis for Upper Punch being
used for Tablet manufacturing
used for Tablet manufacturing
�The Data that is required for analysis, is
�Material Properties (Young’s Modulus, Poisson's Ratio,
Yield Strength, Ultimate Strength)
�Component Drawings
�Boundary Conditions
CASE Study 3D M

�Vaftsy was provided with
drawings for the Upper
Punch
�These Drawings were
converted in to Model
converted in to Model
using software CATIA
CASE Study -Meshing
�The CATIA Model, was
imported into
HYPERMESH and a
Graded Mesh was
generated for it.
generated for it.
Case Study -Solution
�The working conditions
were then simulated on
ANSYS, by applying
suitable Boundary
Conditions
Conditions
Case Study –Post Proc.
�The results obtained from the FEA analysis were
POST PROCESSED using ANSYS
�The POST PROCESSED plots, give information
about
about
�The Magnitude of Maximum Stresses
�The Critical Locations for Stresses
�The Magnitude and Location of Maximum Deformation
�The Directional Deformation Plots
Case Study -Results
�Deformation Plot
Case Study -Results
�Stress Plot
Case Study –Analysis
�The Results highlighted critical sections in the Punch,
which were at the Punch Tip
Case Study –Analysis
�The Directional Deformation results were more
conclusive, indicating, eccentric deformation at the
pentagon tip region than at the base
Case Study –Analysis
�The Initial Analysis, indicated that the full load of
the machine, was detrimental to performance of
the component
�Secondary Analysis was performed on the model,
to ascertain the safe limit of force.
Secondary Analysis was performed on the model,
to ascertain the safe limit of force.
�The understanding of the Initial Analysis was
crucial for finalizing the parameters for Secondary
Analysis
Case Study –Findings
�The Upper Punch might be
getting damaged because of
eccentric deformation at
pentagon tip.
�It was essential to analyze the
Lower Punch for confirming
Lower Punch for confirming
presence of eccentricity.
�The eccentric deformation is
a direct result of the tablet
shape.
�Specifically the relief of the
tablet surface, which leads to
weakening of the tip region
Case Study -Recommendations
�Lower the force of impact. The process gives
acceptable results at 40% of total force.
�Change the relief of the tablet surface.
�Analysis of the lower punch will shed more light
�Analysis of the lower punch will shed more light
on the performance of the Punches.
FEA Benefits
�Modeling –
3-D models are easy to manipulate for
design improvements
�Analysis of design-
New products can be simulated
virtually, to anticipate and solve potential problems.
�Wastage of time in prototyping is cut down.
�Wastage of time in prototyping is cut down.
�Understanding phenomena, empowers one to modify
design.
�Time gap between conception phase to product release is
reduced tremendously.
�In summary, it is an efficient and cost effective design
methodology.
