Weaver Engineering

Focuses on the engineering, prediction, and design of load-bearing welded apparatus and machinery. Structural assessments are performed against severe static and fatigue loading criteria using advanced finite element simulations.

• Weld Joint Detailing

  Establishes optimized joint geometry and selects load-bearing materials compatible with fabricator preferences and design strength requirements.

• Welding Code Compliance Evaluation

  Evaluates structures for conformity with rigorous industry codes including AWS D1.1, AWS D1.2, AWS/AASHTO D1.5, API RP-2A-LRFD, AISC, and ASME guidelines.

• Weld Stress Analysis Courses

  Provides specialized one- to two-day training courses covering classical weld analysis and computer-modeled stress assessment for static and dynamic design.

Applies numerical modeling techniques to evaluate complex mechanical behaviors. Studies include linear and non-linear structural behavior, transient dynamic events, and thermodynamic conditions.

• Non-Linear Material and Plasticity Modeling

  Simulates structural reactions involving material plasticity, creep, thermodynamic cycles, and progressive damage accumulation.

• Custom FEA Tools and Scripting

  Develops specialized calculating tools and custom macros for commercial FEA solvers including Ansys, Geostar, Femap, STAR-CCM+, and STAR-CD.

Analyzes structures under cyclic loading to predict design life, crack initiation, and propagation behavior. Assessments incorporate physical material variables and inspection reliability metrics.

• Crack Growth and Fracture Computations

  Performs computations based on fracture mechanics to assess the growth rate of flaws and evaluate overall structural integrity under damage-tolerant criteria.

• Cycle Counting and Damage Accumulation

  Utilizes stress-life methods and cumulative fatigue algorithms to estimate total cyclic life and compute effective notch stresses.

• Accelerated Life Testing Design

  Creates statistical models and testing protocols for physical components to validate fatigue performance within compressed schedules.

Acquires empirical performance data through laboratory setups and field instrumentation. Instrumentation tasks support the validation of computer-simulated behavior.

• Specialty Transducer Engineering

  Designs and manufactures custom transducers to measure physical parameters such as displacement, multi-axis loads, fluid flow, and coupled mechanical motion.

• Data Acquisition and Microscopic Inspection

  Deploys high-speed precision data logging systems, thermocouple networks, and digital stereomicroscopes to capture material and system diagnostics.
