The Business Value of Finite Element Analysis
The demand for consulting engineers that specialize in Finite Element Analysis (FEA) has increased dramatically as the sector’s technology and products become more potent and advanced.
Companies and engineers may now utilize sophisticated software to more accurately predict how items will behave under a variety of physical settings thanks to the development and enhancement of computer tools.
By means of advanced computational analysis and 20+ years of finite element analysis consulting, our engineers will assist your team in making knowledgeable, and timely engineering design decisions to fulfill project deadlines.
With competitive market rates, businesses can overcome challenging structural engineering challenges at a reasonable budget.
Crack Initiation Life Analysis in Aluminum Structures
Predictive engineering, or assessment of potential failures via fracture mechanics, is a core component of SimuTech Group’s finite element analysis consulting services.
Our knowledge in fracture mechanics has been accumulated in the lab, in the classroom, and most importantly, on the job (in the field).
We have worked on several complicated projects involving satellites, jetliners, airplanes, submarines, and naval ships. In addition, we never lose sight of core methodologies relevant for multi-part analyses (e.g. the fact that a tensile stress field (Mode I) is necessary for a crack initiation).
Consequently, close attention is allotted to the presence of environmentally generated stress corrosion cracking. This applies to both Griffith-Irwin theories and equations, as well as and XFEM and partition of unity.
Composite Overwrapped Pressure Vessel (COPV) Damage Tolerance Assessment
A steel or aluminum liner is commonly used in Composite Overlay Pressure Vessels (COPV) Type 3 & Type 4.
Utilizing a metallic liner has several benefits, one of which is the ability to perform an autofrettage treatment on the liner to induce compressive stress. The damage tolerance of the liner during operation is significantly increased by autofrettage.
From autofrettage through burst prediction, the study of COPV Type 3 and Type 4 cylinders for aerospace applications is wholly nonlinear.
At operating levels, the progressive damage analysis (PDA) material-model generated in ANSYS Mechanical enables material parameters to be calculated.
Subsequently, employing holistic FEA stress figures, which guide optimal design suggestions.

How Finite Element Analysis Consulting Can Help your Business
FEA or Finite Element Analysis consulting engineers employ mathematical models to understand and quantify the effects of real-world conditions on a part or assembly, particular to the business’ operation.
These simulations are functionally coordinated for the individual business needs. Then, conducted via specialized FEA software. This enables engineers to locate potential problems in a design, including areas of tension and weak spots.
Here’s the bottom line…FEA is predictive but not affirmative. Therefore, those without years of experience in finite element analysis should not be making core operational/process changes.
Don’t mistake our message, we strongly recommend employing an in-house FEA/FEM software. Moreover, in some cases, the in-house expertise is not available to ensure computations and models have been contextualized. That is, defined accordingly to the particular variables of the business (machines, materials, regulations). And, a full-scale reorganization based on analysis missing one core variable, for example, could cost the organization millions of dollars.
Custom FEA Design
In addition, finite analysis does not ascertain that a design will withstand the simulated stresses with sweeping certainty; It merely gives engineers a view of how the particular design may behave. That is, with the imposed stresses by the variables input by the engineer. This is crucial to understand, for the industry at large. A computational analysis or modeling software is only as good as the engineer guiding the simulation.
The core distinction between an FEA engineer (day-go-day employee) and an FEA Consultant is in how they look at software, and approach the engineering problem at hand.
FEA consultants, primarily, look at these from the business side. Specifically, with an emphasis on operational expenses, manufacturing or process logistics, and overall department ROI.
Conversely, engineers (day-go-day employees) tend to look at software from a scope of functionality and application. This, of course, is essential to developing the product(s) efficiency, and applicability for a diverse array of industries. However, may diverge from the bottom-line financial business goals of the company.
FEA, and the supporting software in which it is employed, enables engineers to conduct the simulation of a designed model. This is, of course, in place of having to create a physical model for testing purposes on an FEA project.
- This offers financial incentives in reducing operation expenses.
FEA & FEM
However, FEA offers more advantages.
- The FEM (finite element method) employed by our consulting engineers during analysis, permits modeling of a diverse number of material types. In addition, the ability to monitor and ‘audit’ how confined effects impact a small area of design. This is particularly relevant in more complicated geometry types.
FEA’s expansive scope of application
Business’ in non-engineering sectors are often surprised how Finite Element Analysis & modeling can significantly enhance their day-to-day operations for a wide range of tasks.
The fields of healthcare and automotive are frequent clients, which are handed off from our fluid dynamics engineering segment. One recent instance involves the deformation of a vehicle from collision and stress on human bones. Rather than just theoretical examination, a practical utilization of finite element modeling (FEM) software by our consulting engineers.
FEA (finite element analysis) is recognized in the engineering industry as one of the most dynamic and robust features applied to CAD (Computer-aided design).
FEA is essential to CAD for measuring an object. Specifically, via application of finite elements that contain small rectangular and triangular shapes.
To analyze the whole object, our FEA engineering consultants will analyze each finite element in the entire object network. From here, mapping the corresponding outcomes which combine to plot the overall behavior of a complex object.
Specific elements will be analyzed for certain property thresholds. This includes stress-strain, thermal properties, dynamics, or any other characteristics required for a contextualized analysis. The bottom-line being to ultimately enhance your business’ day-to-day operations.
