Understanding Failure Through Engineering Analysis
FEA and mechanical engineering consultancy for investigating structural performance, failure mechanisms and design risk.
QANTIS Engineering Group combines advanced FEA with engineering judgement to turn complex structural behaviour into clear technical conclusions and practical recommendations.
When the design needs more than a calculation
Whether you're validating a new component, investigating a failure, reducing weight or checking a design before manufacture, the important question isn't simply what the simulation shows.
It's what the results mean for the engineering decision.
What We Do
Delivering for Our Clients
Advanced failure analysis through FEA to understand how designs behave, why they fail, and how they can be improved.
01 — Structural & Stress Analysis
Assess how components, assemblies and structures respond to applied loading. QANTIS evaluates stress, strain and load paths to identify critical regions and understand the underlying structural behaviour. Analysis can be used to validate existing designs, investigate unexpected performance, assess design changes and support decisions before manufacture. Particular attention is given to whether the model, loading and constraints represent the real engineering problem and whether the resulting stresses are meaningful for the design.
02 — Structural Optimisation
Improve structural performance while reducing unnecessary material, weight or cost. QANTIS uses FEA-driven optimisation to identify where material contributes to structural performance and where it can potentially be removed. Optimisation can support early-stage concept development as well as refinement of existing designs, with the resulting geometry assessed against relevant loading and performance requirements. The objective is not simply to produce a lighter structure, but to understand the trade-offs between weight, stiffness, strength and manufacturability.
03 — Thermal & Thermo-Mechanical Analysis
Understand how temperature and temperature gradients affect structural performance. QANTIS assesses thermal expansion, temperature distribution and the resulting stresses and deformation where mechanical and thermal behaviour interact. This can be important where components experience elevated temperatures, significant temperature changes or constrained thermal expansion. The analysis helps identify thermally driven failure mechanisms, assess the interaction between thermal and mechanical loads, and determine whether a design is likely to maintain its required performance under representative operating conditions.
04 — Pressure & Piping Analysis
Assess the structural response of components and systems exposed to internal or external pressure. QANTIS evaluates stress, deformation and localised behaviour in pressure-containing structures, including the influence of geometry, loading and constraints. Analysis can help identify critical regions, assess pressure-induced deformation and investigate potential failure mechanisms. It can also support design verification and modifications where pressure loading is a significant part of the operating environment.
05 — Buckling & Stability Analysis
Determine whether a structure can remain stable under compressive or destabilising loading. Buckling can occur before material strength is reached, making conventional stress analysis insufficient for slender or stability-sensitive structures. QANTIS assesses both the predicted buckling behaviour and the sensitivity of the structure to imperfections, loading and boundary conditions where appropriate. The results can support decisions around geometry, stiffness, reinforcement and safety margins, helping identify designs that may be vulnerable to sudden loss of structural stability.
06 — Deflection & Deformation Analysis
Evaluate how much a component or structure moves under load and whether that movement is acceptable for its intended function. Excessive deformation can affect alignment, clearances, sealing, contact, assembly and overall product performance even when calculated stresses remain below material limits. QANTIS assesses displacement and deformation throughout the structure, identifying areas of significant movement and the factors driving it. The results can support decisions around stiffness, geometry, material selection and structural reinforcement.
07 — Assembly & Contact Analysis
Understand how components interact, transfer load and influence one another within an assembly. Contact behaviour can significantly affect local stresses, load paths, deformation and overall structural response, particularly around interfaces, fasteners, joints and mating surfaces. QANTIS uses FEA to investigate these interactions and assess how loads are transferred through the assembly. This can help identify localised loading, separation, sliding or unexpected contact behaviour that may not be captured by analysing individual components in isolation.
08 — Fatigue & Durability Analysis
Assess whether a component can withstand repeated or cyclic loading over its required service life. A design may perform adequately under a single static load while remaining vulnerable to fatigue failure after repeated operation. QANTIS evaluates cyclic loading conditions and identifies regions where fatigue damage may accumulate, helping determine likely fatigue-critical locations and assess durability. The analysis can support design changes, load-cycle assessment and investigations into components that have experienced cracking or premature failure.
09 — Composite Structure Analysis
Assess the structural behaviour of composite components where material direction, laminate construction and failure mechanisms influence performance. QANTIS can evaluate stresses and strains through composite laminates and investigate how loading is distributed between individual plies and orientations. Analysis can support decisions around ply arrangement, laminate thickness, stiffness and structural performance. Where appropriate, the assessment can also consider potential failure mechanisms such as fibre or matrix failure and interlaminar behaviour.

Advanced failure analysis through FEA to understand how designs behave, why they fail, and how they can be improved.
At QANTIS ENGINEERING GROUP, we support engineers, startups, and product designers in making confident, data-driven decisions—eliminating guesswork from the design process. Too often, products move into prototyping without proper validation, resulting in costly failures, project delays, and avoidable redesign cycles.
If you’ve ever questioned whether your design will withstand real-world loading conditions, been concerned about the cost of failed prototypes, or hesitated before committing to manufacturing, you’re not alone. These challenges are common—and precisely what we are equipped to address.
Our team consists of highly skilled mechanical engineers with extensive experience in design, simulation, and real-world product development across a range of industries. Using industry-standard tools such as SolidWorks for advanced CAD modelling and ANSYS for high-fidelity finite element analysis, we deliver accurate, reliable insights grounded in engineering best practice.
We combine technical depth with a practical, application-focused approach—ensuring every analysis not only identifies potential failure points, but provides clear, actionable recommendations that improve performance, reduce risk, and support successful product development.
