Structural and Stress Analysis

Strength Under Pressure: Structural and Stress Analysis

At Dayton T. Brown, Inc., we specialize in structural analysis to predict performance, diagnose failures, and ensure designs withstand real-world stresses. Our expertise includes strain gaging, calibration, and comprehensive structural testing, from tensile strength assessments to advanced simulations. By analyzing test data and correlating results, we create virtual models that drive smarter, more efficient design optimization.

Structural and Stress Analysis Solutions

Structural Analysis
Evaluate strength, stability, and performance under various loads.

We provide comprehensive structural analysis, including linear and non-linear evaluations of components and systems under static, dynamic, and thermal loads. Our team delivers engineering solutions backed by analytical calculations, technical reports, and validation of design performance against shear, moment, and torsion requirements. We also determine load paths, buckling loads, and creep effects at varying temperatures to ensure structural integrity.

Stress Analysis
Prevent, Predict & Optimize Structural Performance


DTB offers expert stress analysis to design, verify, and troubleshoot structural issues. Using finite element analysis (FEA) and classical hand calculations, we predict fatigue life and optimize designs. Our process includes full stress mapping, load reactions, failure mode evaluations, and life extension strategies. Past projects include fatigue life prediction for carrier aircraft arresting gear and seismic evaluations for electrical equipment.

Design Simulation & Finite Element Analysis (FEA)
Streamlining design with accurate simulations, validation, and 3D modeling.


Our FEA services enhance product development by reducing design cycles and accelerating verification. Utilizing ANSYS and Autodesk Inventor, we conduct static, dynamic, modal, and random vibration analyses. We validate simulations through empirical testing, ensuring accuracy and compliance. Our design support includes conceptual modeling, 3D solid modeling, and assembly detailing.

Damage Tolerance Analysis
Assessing Load Capacity After Damage


DTB specializes in damage tolerance assessments, evaluating a structure’s ability to withstand operational loads after sustaining damage. We conduct crack growth tests to analyze the impact of load frequency and environmental factors, correlating real-world test data with analytical predictions. Our expertise in hybrid testing and engineering ensures precise life extension evaluations.

Vibration Analysis for Predictive Maintenance
Detect stress points and predict failures to enhance product longevity.


Our vibration analysis services help identify stress points, predict failures, and implement preventive design improvements. Using FEA, we model structural dynamics and simulate real-world operating conditions to detect excessive vibrations. Our in-house vibratory testing facilities allow us to assess component responses to shock and vibration, optimizing product longevity.

Failure & Fatigue Prediction
Predict lifespan and enhance durability.


We perform fatigue life predictions using strain, stress, and load life methodologies, incorporating both test data and finite element modeling. By developing load spectra and conducting field strain gage measurements, we accurately estimate component lifespan and recommend design enhancements to extend durability and performance.
