SFDesign makes extensive use of Finite Element Analysis (FEA) to design and verify the structural integrity of products/structures.

Solid/Surface 3D Models

Solid and surface models are use to quickly determine the response of a structure under design loads. The aim of these models is to accurately capture the physics of the problem that is being solved.
At SFDesign, we believe our FEA models should simulate reality as closely as possible and our engineers, with years of experience, make this possible.

Linear & Non-linear static analysis

Most FEA analyses are performed in the linear domain with stresses capped to the allowable stress depending on the standard that governs the design.
A non-linear analysis is used for standards that follow the limit state design. A non-linear analysis looks into the structural integrity of the design as it approaches the materials yield stress and even past its yield point.

What is Dynamic Analysis?

Dynamic Analysis is performed for structures undergoing time-varying loads where the inertia of the structure becomes a factor.
Dynamic analysis is also used when analyzing parts that will be mounted on moving vehicles, for example on mining trucks, offshore structures, rolling stocks, road trains, and more.
Frequency, spectral and harmonic responses look into the amount of energy that is transferred to a structure and its response. The difference between these analyses is the manner the energy is classified, whether its a frequency extracted from a time-history analysis or spectral energy or in a cyclic manner.
Drop test analysis is commonly done to determine product usability once it has fallen to the ground. The analysis is capable of pin pointing the weak spots in a design.

Buckling/Post-Buckling

A Buckling Analysis determines the load a slender structure can withstand before it buckles. This is a common analysis for tanks.
A Post-Buckling Analysis determines the structural integrity of the structure once it had buckled. This is commonly done for tanks which have had a portion of the structure buckle and yet the post-buckling analysis has shown that the tank still has adequate capacity to operate.

We Offer

SFDesign has a blend of both experienced senior and talented young engineers who can quickly design and verify conceptual ideas or grind out the nitty-gritty engineering calculations needed to engineer a product. Our engineers use a combination of engineering calculations and Finite Element Analysis (FEA) to perform their analysis.
FEA helps us to discover and test unique solutions to unique problems. FEA also helps in optimizing product weight through topological optimisation.

When you get SFDesign to design a product for you, we take a holistic view of the design.

We look at:

1. Structural Integrity - is it strong enough?
2. Dynamic Behaviour - under vibration, will it resonate and fail?
3. Fatigue - how long of a design life does it have?
4. Drop Test - what happens to the product if its accidentally dropped? Can it still be used? Where's the weak points in the design?
