Finite Element Analysis
The New Way to success. advance. progress.
The next decade is going to be about reverse innovation - design and build products in emerging markets, for emerging markets and for the developed economies as well. We are moving beyond traditional levers like cost-cutting and focus on leveraging flexible capacity, access to emerging markets and reduced cycle time to drive business growth and innovation.
Finite Element Analysis(FEA)
It is a great feeling to finally have an innovative design in hand. We are sure that the new product design is way ahead of today’s best products.
But how to know if this ground breaking design stands the loading conditions in reality? How will the thermal aspects of the environment affect the product behaviour? What happens when the thermal stress and structural loading acts simultaneously on the product?
The usual method of prototype testing to know the answers for the above questions are both time consuming and highly expensive. Employing the alternative ways that provides key insights to the product behaviour early in the process is necessary to develop high performance products with reduced development schedules.
We can help our clients to analyse their designs using the latest FEA methods. FEA is used to validate the product design and reduce the cycle time drastically by eliminating any design errors early in the process. We can apply a vast number of loading conditions and other test cases to know the product behaviour.
Our dedicated team endeavours to improve design improvement from all aspects. We work with companies of all sizes to address their needs in FEA. It is with great pleasure that we offer outsourcing services for a wide range of industries including automotive, heavy equipment, aerospace etc.

Our FEA Services:
LINEAR ANALYSIS
Linear analysis is the best way to get the process started. This level of analysis is meant to simulate very small loads and deflections. The pre-requisite is that the loads being applied do not deform the material permanently. These cases refer to conditions where the material is within the elastic limits.
Linearity is just an assumption we make to simplify the modelling in general. “Linearity” comes from our efforts to simplify the complicated equations in order to create a workable engineering model.
We provide our clients with the Linear Analysis services when the design specifications allow the material to remain inside the elastic limit and to study the effects of small deformities and deflections. We identify the stress concentrated regions and possible areas where abnormal deformations may occur. This can help our clients to establish necessary safety criteria for the product. In case of several non-linearities in the system, our experts suggest the necessity for non-linear analysis.
NON-LINEAR ANALYSIS
In real life scenarios, the components are subjected to loads well beyond their yield strength. There are other factors such as thermal stress, friction between two surfaces, combination of parts with different yield strength etc that may affect the behaviour of the component. All these parameters cannot be analysed using the Linear Method.
Parts withstanding loads beyond the yield point may experience an hardening or cracking and it will start losing its stiffness. Thus most of the times, its not just enough to analyse the design in a linear fashion. For heavy duty and critical components, we must see how the material behaves in different loading conditions. The non-linear analysis incorporates all the specifications that may affect the component and provides the result.
We have specialists in performing Non-Linear analysis on engineering structures who can help our clients predict the product performance that ranges from the no load condition till the product failure stage. We single out the areas which are subjected to high stress and deformation . Based on all the findings we suggest feasible product improvements to eliminate the defects.
MODAL ANALYSIS
Our Modal Analysis services provide our clients with an effective tool to visualise the vibration performance of their products. The procedure can be used to determine various factors that may affect the vibratory behaviour of the product such as resonant frequency, damping values, structural deformation patterns etc.
This helps us to zero in on the root cause of the problem if the product exhibits unwanted vibratory behaviour. With the root causes identified we suggest rectification and design changes that must be made to eliminate unwanted vibrations. Modal analysis also identifies the “Sweet Spots” on the structure where the vibration is minimum. These spots may be used as the locations for critical equipment for stability.
CRASH ANALYSIS
Crash Analysis is done to evaluate the product behaviour during a high impact collision and ensure that the applicable safety standards are met. Using the FEA techniques, engineers can simulate the crash conditions and generate in depth findings with respect to how the product responds to specific crash conditions. It also helps to make critical design changes to make the product safer and stronger.
Another benefit of subjecting the product to crash analysis is that the manufacturers can determine the crashworthiness of the proposed design and allow them to choose alternative production methods or materials that may augment the survivability of the product. It also empowers the clients to make design changes easily without the cost incurred in destructive testing.
Engineers provide the most comprehensive crash analysis services to retrieve key information about the effect of crash or impact loads. Our crash analysis conforms to the standards laid by the global authorities to make sure that the product meets the global norms for safety.
Our expertise includes:
FATIGUE & DAMAGE TOLERANCE (F & DT)
Fatigue and damage tolerance is one of the most important stages in the product design. Designers face a challenging task to create designs that are fatigue resistant and tolerant to damages. The designers make use of the F & DT principles to define critical structural component lives, and produce an inspection and maintenance schedule to eliminate structural failure. Fatigue analysis is important to prevent failure of a component under repeatedly applied loads. Damage tolerance is the ability of the product to resist fracture from the pre-existing cracks for a given period of time.
In today’s competitive markets the users expect the product to perform their functions satisfactorily beyond the intended product life. Hence the companies must make sure that their products are designed in such a way that the material properties are evaluated as precisely as possible within all the environmental conditions to avoid failures.
We extend fatigue analysis services to determine causes of the failure and to address design and structural issues. It thus ensures optimal material selection and reduces repairing and re-designing costs. With years of experience and insight of fracture mechanism and crack infiltration & growth, allows us to carry out FEA analysis and physical testing in best possible manner.
