Our FEA Services and Engineering Analysis Capabilites

Structural Analysis & Stress Assessment

Understanding how a component or assembly behaves under load is fundamental to making confident engineering decisions.

QANTIS Engineering Group provides consultancy-grade structural analysis and stress assessment services to help engineering teams evaluate performance, identify critical stress locations, and validate designs before manufacture.

We assess structural behaviour under realistic operating conditions, providing practical engineering insight that supports design development, risk reduction, and product validation. Our focus extends beyond generating simulation results — we interpret structural response and provide recommendations that inform engineering decisions.

Our structural analysis capabilities include:

Linear static stress analysis

Design validation studies
Comparative design assessment
Engineering reporting and recommendations

Whether validating a new design, investigating a structural concern, or reducing development risk before production, we provide the engineering insight needed to support confident decision-making.

Deflection & Deformation Assessment

Structural integrity is not defined by stress alone. In many applications, excessive deflection or deformation can compromise performance, alignment, functionality, and reliability long before material failure occurs.

QANTIS Engineering Group provides consultancy-grade deflection and deformation assessment services to help engineering teams evaluate structural stiffness, displacement behaviour, and performance under operational loading conditions.

We assess how components and assemblies deform under realistic loads, identifying areas where excessive displacement, distortion, or loss of stiffness may affect product performance.

Engineering reporting and recommendations

Whether validating a precision assembly, assessing structural rigidity, or ensuring performance under load, we provide the engineering insight needed to support confident design decisions.

Assembly & Contact Behaviour

The structural performance of an assembly is often governed by the interaction between components rather than the strength of the individual parts themselves.

QANTIS Engineering Group provides consultancy-grade assembly and contact behaviour assessment services to help engineering teams understand load transfer, contact interactions, joint performance, and structural behaviour under realistic operating conditions.

We evaluate how components interact within assembled systems, assessing the effects of contact conditions, friction, preload, and load paths to provide practical engineering insight for design validation and performance assessment.

Our analyses help identify critical interfaces, reduce uncertainty, and support informed engineering decisions before manufacture.

Engineering reporting and recommendations

Whether assessing a slender structure, validating a load-bearing component, or investigating potential instability, we provide the engineering insight needed to support reliable and confident design decisions.

Fatigue Assessment

Structural performance is not defined solely by static strength. Components subjected to repeated loading can experience fatigue failure over time, making fatigue assessment a critical part of product validation and reliability engineering.

QANTIS Engineering Group provides consultancy-grade fatigue assessment services to help engineering teams evaluate structural durability, predict fatigue life, and reduce the risk of in-service failure.

We assess the effects of cyclic loading, stress concentrations, and operational conditions on component performance, providing practical engineering insight that supports design validation, reliability improvement, and informed engineering decision-making. Our analyses help identify critical locations, assess service life, and improve confidence before manufacture.

Testimonials

James Carter

Product Design Engineer, Manchester, UK

“We needed to validate a load-bearing bracket before committing to manufacturing. The analysis was delivered quickly and highlighted a critical stress concentration we had completely overlooked. The recommendations were clear and easy to implement—this likely saved us a costly redesign later in the process.”
