VGO bases its work on measurable, independently verifiable data, with careful documentation and rigorous analysis throughout each project.

Strain gaging

• Application of strain gages to real-world structures in the field and in the lab
• Real-time, non-destructive measurement of stresses in components and structures
• Used to validate engineering calculations and finite element analysis (FEA) models

Physical testing

• Specialized, low-volume and one-of-a-kind tests tailored to specific client objectives
• Use of conventional and custom-built load frames for static and fatigue testing
• Custom test procedures developed when standard tests do not exist or are not sufficient

Field inspections

• Non-destructive testing (NDT) and field assessments of industrial equipment
• Identification of cracking, misalignment, corrosion, and wear before serious damage occurs
• On-site engineering interpretation of findings to prioritize which issues require immediate action

Failure analysis

• Metallurgical and mechanical analysis to determine modes and causes of failure
• Integration of lab analysis, stress analysis, and inspection data
• Development of corrective and preventative strategies to reduce the chance of repeat failures

VGO emphasizes practical, data-driven solutions and mobilizes quickly to address urgent engineering problems.

VGO goes beyond traditional lab work by integrating stress analysis, strain gaging, and inspection capabilities. This broader approach allows VGO to:

• Identify the primary mode of failure
• Determine contributing factors and service conditions
• Propose mitigation strategies to prevent similar failures in the future

Failure analysis services

• Fracture analysis
• Corrosion analysis
• Weld evaluation
• Material identification
• Root cause analysis
• Flaw identification

By leveraging metallurgical knowledge, analysis capabilities, and instrumentation expertise, VGO can assist with design modifications, suggest material and processing changes, and help implement monitoring and early-warning solutions so that the analysis does not end until the root cause is addressed.

VGO focuses on specialized, low-volume, and one-of-a-kind tests that require engineering judgment and careful setup rather than high-volume standardized testing.

Equipment and capabilities include:

• Static loading (test frames up to 120,000 lbf)
• Dynamic loading
• Fatigue testing (equipment up to 20,000 lbf)
• High-speed data acquisition
• Field instrumentation
• Custom test procedures

VGO also maintains an on-site machine shop to build and modify fixtures and uses a range of actuators and instrumentation to monitor, measure, and control test parameters.

Field inspections

VGO combines non-destructive testing (NDT) with engineering analysis to support both routine maintenance and troubleshooting of production problems for industrial equipment.

Field inspection services include:

• Non-destructive testing (NDT)
• Fitness for purpose evaluations
• Increased capacity assessments
• Remaining service life estimates
• Allowable crack size evaluations
• Crack repair procedure guidance
• Health monitoring

By pairing engineers with NDT technicians, VGO can interpret indications in real-time, helping clients decide which issues require immediate repair, which can be monitored, and how best to reduce downtime and cost.

VGO maintains an extensive inventory of strain gages and data acquisition equipment, allowing the team to respond quickly to client needs and perform measurements in challenging field environments.

Strain gaging services

• Validation of finite element analysis (FEA) models
• Structural health monitoring
• Custom load cells
• Bascule leaf bridge balancing
• Residual stress measurement
• Dynamic and static load determination

These services provide practicing engineers with the stress and load data they need to make reliable design, maintenance, and operational decisions.

Ask anyway — the agent will say plainly that it is not published rather than guess.
