What We Do
Deflection and Deformation Assessment
Deflection and deformation assessment is used to understand how much a component or structure moves, bends or changes shape under its operating loads.
A component does not need to fail structurally to cause a problem. Excessive deformation can affect alignment, clearances, interfaces, sealing, motion, assembly and the overall performance of a product.
QANTIS Engineering Group provides consultancy-grade Finite Element Analysis (FEA) and deformation assessmentto determine whether predicted movement is compatible with the functional requirements of the design.
Typical engineering questions include:
How much will the component deflect under load?
Is the predicted deformation acceptable?
Will movement affect alignment or clearances?
Could deformation interfere with another component?
Is the structure sufficiently stiff?
Where does the majority of the deformation occur?
Would a geometry change improve stiffness without adding unnecessary material?
The objective is to understand how a structure moves under load and whether that movement matters to the product.
Why This Analysis Matters
Strength is only one measure of structural performance. A component can remain well below its material strength limit while deforming enough to affect its function.
Deflection and deformation assessment can help engineering teams:
Verify stiffness requirements against defined performance criteria
Identify excessive movement before it causes functional problems
Assess alignment and clearance under operating loads
Understand structural stiffness and how loads influence deformation
Improve designs through changes to geometry, section thickness or load paths
Reduce unnecessary material where stiffness can be achieved more efficiently
The significance of deformation depends on what the component is required to do. A few millimetres of movement may be acceptable for one structure but unacceptable for another where precision, sealing or alignment is critical.
The important question is not simply how much a component moves, but whether that movement affects its intended function.
