Bolted Joint Design & Analysis
Bolts have been around since the dawn of the Industrial Revolution. They are still widely used to join components in modern products, which is unsurprising since they are low-cost and easy to assemble and disassemble. Reliable bolted joints can only be achieved through proper design, assembly, and testing.
Industry-Leading Bolted Joint Consulting Services
Matrix Engineering Consultants has proven expertise in solving mechanical and structural bolted joint challenges through rigorous analysis and can provide independent, impartial advice. Our extensive experience and in‑depth knowledge enable us to deliver industry‑leading bolted joint consulting tailored to demanding applications where mechanical and structural joint performance is critical.
When it comes to mechanical and structural bolted joint design and analysis, our experience is unmatched. Here’s what our consulting services include:
Torque Tension Testing Services
Matrix has the capability and experience to conduct torque-tension testing according to industry standards, such as ISO 16047 Torque/clamp force testing.
VDI-2230 Based Bolted Joint Analysis
We use sophisticated methodologies based on the established VDI-2230 Part 1 and 2 standards. (Systematic calculation of highly stressed bolted joints)
Fastener Loosening Solutions
We have extensive experience characterizing fastener-loosening behavior, identifying causation, and developing mitigation and/or solutions.
FEA Modeling of Complex Bolted Joint Systems
Utilizing non-linear finite element analysis techniques, our team can characterize joint reactions and behavior and predict common failure mechanisms.
Failure Investigations
Matrix is well-suited to lead independent and impartial failure investigations. Our structured analysis process allows us to establish the causation and root cause of the failure mechanism and justification for proactive remedies and improvements in joint reliability.
Strain Gauged Bolts
We provide custom strain-gauged bolts for precise measurements in bolted joints. Our solutions help engineers optimize joint performance, prevent failures, and integrate data seamlessly into testing & design protocols.
Assembly, Service, and Field Issue Resolution Services
We specialize in resolving challenges related to bolted joints during assembly, service, and field environments and developing torque auditing strategies.
Fastener Specification Consulting
Beyond size and strength, we offer expert insights into cost-effective fastener specifications aligned with industry consensus standards.
