Products and components must not only work — they must last.
At Product Development Engineers Ltd, we help you assess, analyse, and improve the durability, strength, and lifetime reliability of your designs.
Whether you are developing a new product, investigating failures, or optimising an existing design, we offer both expert consultancy and hands-on engineering analysis to support your project.
We specialise in Finite Element Analysis (FEA), Fatigue Analysis, and Fracture Mechanics, delivering practical insights that help you design more reliable products and processes.
Engineering Life and Reliability Services
We work with engineers to deliver:
- Life assessment of components and assemblies
- Reliability improvement in mechanical designs
- Fatigue life estimation for critical parts
- Fracture risk evaluation and defect tolerance analysis
- Failure investigation and root cause analysis
- Qualification and validation support for demanding operating environments
Whether you need technical advice, full analysis execution, or both, we provide flexible support based on your project needs.
Finite Element Analysis (FEA)
Finite Element Analysis (FEA) is a critical tool for predicting real-world behaviour under stress, vibration, thermal loads, and other conditions — without the need for costly early prototypes.
We provide:
- Linear and nonlinear stress analysis
- Contact, material, and geometric nonlinearities
- Thermal-mechanical coupling studies
- Modal and vibration analysis
- Stress concentration identification and mitigation strategies
We don’t just model — we interpret the results and translate simulation data into practical design recommendations, ensuring that FEA directly improves your engineering outcomes.
Fatigue Analysis
Many mechanical failures are caused not by one overload, but by cyclic fatigue.
Our fatigue analysis services include:
- Estimating fatigue life using FEA stress results
- Selecting appropriate S-N curves and applying Goodman or Haigh corrections
- Identifying fatigue-sensitive areas and critical stress raisers
- Supporting the design of accelerated life testing programmes
- Recommending material improvements or design modifications to extend life
We help you understand where, how, and when fatigue failures could occur — and how to prevent them through smarter design and material selection.
Fracture Mechanics
Cracks and flaws — whether introduced during manufacturing or in service — can severely limit product life.
We offer fracture mechanics consultancy and analysis, including:
- Defect tolerance studies and critical flaw size evaluation
- Stress intensity factor (K) and fracture toughness (K_IC) calculations
- Crack growth prediction under cyclic loading
- Residual life estimation for components with known defects
- Advising on fracture-critical design improvements
By linking theoretical fracture mechanics to real-world application, we help you manage defect risks, predict safe service intervals, and optimise durability.
Why Work With Us?
- Consultancy plus execution: We advise, model, and analyse — delivering both strategic insights and detailed technical work.
- Experienced engineers: Practical, real-world experience across R&D, product development, and manufacturing environments.
- Tailored support: Flexible services to suit early-stage projects, troubleshooting work, or full qualification testing support.
- Clear results: Actionable conclusions, not just raw simulation data.
Our services help you accelerate development, reduce failure risk, and build lasting product success.
