Damage Tolerance capabilities include crack growth based life prediction, crack propagation failure analysis, and product life extension.


Helping you do things better

Identification of Efficiencies

Provide an independent assessment of the combinations of methods and tools you’re using to solve a given problem. That allows us to identify opportunities for efficiency gains through automation, process and quality control.

Alignment of Technical & Business

Engineering processes cost money, but also make money. Process improvement is carried out through alignment of technical and business objectives to ensure any proposed improvements make financial sense.

Doing Things Right

Successful engineering process improvement is itself a process. Using well-known methodologies in a structured approach ensures following something as fundamental as ‘plan, do, check, act’ yields positive results.


The key to unlocking efficiency

In-house & External

Automation methods and tools are used extensively in-house to improve productivity, maintain processes and ensure quality. Quartek offers these same benefits through automation to you.

Off the Shelf or Custom Made

A range of tools have been developed for a wide variety of applications including reporting, data extraction and input file creation. Whilst many of these tools are available off-the-shelf for client use, if you require a custom solution, we’ll create it.

Single-Step through to Complete Solutions

From the simplest single step process, coded to achieve robust and consistent results, through to complete, fully developed and integrated solutions, regardless of how simple or complex, we can create it to meet your requirements. Applications are typically developed in VBA, maintaining compatibility with Excel.


Take advantage of our experience

Strategic Analysis Advice

Provide advice for your business, department or project, aligning your longer-term strategic engineering goals with the most suitable analyses, solution methodologies and processes required to achieve those goals.

Design to Manufacture

Ensuring the success of your manufacturing program by advising on the most suitable analyses, tools and processes required prior to cutting, as well as helping you plan to manage and minimise issues once production is underway.

Operation & Maintenance

Advice on analysis methods, repair strategies, usage monitoring processes and structural testing programs to assist with your ongoing product support, operation and maintenance.
