This year, I am pleased to announce that, in a collaboration with SIEMENS and Altair, we will have two pre-conference tutorials on July 29th and 30th. Thanks to SIEMENS’ and Altair’s sponsorship, these tutorials will be offered for free.
July 29th – Modal Analysis, SIEMENS
Structural Dynamics
- Resonances
- Frequency response functions (FRFs)
- Excitation techniques (hammers, shakers, etc.)
Measurement Considerations
- Sampling rate, blocksize, acquisition time
- Bandwidth, spectral lines, frequency resolution
- Window (hanning, flattop, etc.) and leakage
- FFTs, phase, autopowers
- Autopowers vs. power spectral density (PSDs)
Structural Analysis
- Modal curve-fitting techniques
- Modal synthesis
- Modal assurance criterion (MAC)
Structural Analysis
- Modification prediction
- Accelerometer mass compensation
- FE-Test correlation
July 29th – Advanced Processing of CAE and Test Data with Altair Compose
Altair Compose™ is an environment for doing calculations, manipulating and visualizing data (including from CAE simulations or test results), programming and debugging scripts useful for repeated computations and process automation. Compose allows users to perform a wide variety of math & linear algebra (including matrix analysis and differential equations), filter signals, fit polynomials through data, approximate or check results from commercial simulation software, perform optimization. This workshop will be a half day course in the afternoon of the 29th.
July 30th – Durability, SIEMENS
Fundamental Concepts
- Why Predict Product Life?
- Stress, strain, damage, and fatigue life
- Cyclic fatigue versus static strength
Understanding Loads-Test and Simulation
- Load data acquisition
- Strain gauges, LVDT, string pots, load cells, canbus and GPS.
- Data cleanup: Spike removal, drift correlation and anomaly detection
Load Data Processing: Understanding Damage Content an Establishing a Target
- Cycle counting, SN curves, miner’s rule
- Mean stress and other SN curve adjustments
- Rainflow counting and interpretation
- Endurance limit and Haigh-Goodman diagram
Fatigue Life Approaches
- Applications related to spot welding and seam welding
- Load extrapolation: Quantile and statistical various methods

- Load superposition
- Setting targets from customer data
Accelerated Testing and Simulation
- Mission synthesis
July 30th – Meshless Analysis with Altair SimSolid
Altair SimSolid™ is a revolutionary structural analysis software developed specifically for design engineers (recently acquired by Altair). It eliminates geometry simplification and meshing, the two most time consuming and expertise extensive tasks done in traditional FEA. This half day workshop will be offered the morning of July 30th.
July 30th – Topology Optimization with Altair Inspire
Altair Inspire™ software is the industry’s most powerful and easy-to-use Generative Design/Topology Optimization and rapid simulation solution for design engineers. It enhances the concept development process by enabling simulation-driven design to increase your product’s efficiency, strength and manufacturability. This can lead to reduced costs, development time, material consumption, and product weight. This half day workshop will be offered the afternoon of July 30th.
