Finite Element Analysis
FEA
The Finite Element Analysis (FEA) component of SimScale enables you to virtually test and predict the behavior of structures and solve complex structural engineering problems subjected to static and dynamic loading conditions. Our online simulation solution uses scalable numerical methods that can calculate mathematical expressions otherwise very challenging due to complex loading, geometries or material properties.

Finite Element Analysis
Response Dynamics Vibration Engineering, Inc.
An understanding of structural dynamics is very important to sound Finite Element Analysis (FEA). We have been performing FEA analysis for over 30 years and in most cases we have used experimental data to guide our modeling. While our engineers have had undergraduate and graduate courses in FEA, it is the years of modeling and analysis of existing structures that has taught us the most by forcing a thoughtful analysis of the key structural dynamics and then going though the process of making adjustments to boundary conditions, expanding the dynamics of the model in places, and making simplifications and approximations where possible.

Finite Element Analysis
This useful tool will minimize induced stress on the board under test. The 3-D software will account for all components populated on the board, and probe force and push rod locations on the fixture. It uses this information to simulate the actual test to determine which area of the board is enduring too much stress and then provide suggestions to correct the situation. A damaged board could cost upwards of thousands of dollars and lost time. Including Board stress analysis in your test strategy is an excellent way to insure that your new test comes up fast, and without any stress related board damage.

Modal Exciters & Amplifiers
Experimental modal analysis, or modal testing, is a process for physically obtaining a math model of a structure’s dynamic properties. Modal tests identify a structure’s modal properties: natural frequencies, mode shapes, mass, stiffness and damping. Modal test results help troubleshoot resonant excitation from operating forces, validate and verify finite element models, predict the benefits of structural modifications, support design verification, and understand structural responses due to complex loading conditions.

Correlation Analysis
EDM Modal Correlation Analysis allows the user to correlate two modal models; EMA and/or FEA models. Comparing the experimental data with that acquired through finite element analysis helps in validating the test results. Users can import the geometry model and mode shape data from FEA or EMA software. A modal mapping procedure is executed to match the EMA and FEA models. After this matching procedure, the new mode shape information from FEA is interpolated and the FEA modal parameters are displayed alongside with EMA results. Finally, to observe the correlation between the results from the two methods, a Cross-MAC matrix is calculated and shown.

FEA and Strain Gauge Testing
Circuit Check began Strain Gauge Testing in 1999 when BGA/SMT technology started replacing PTH components, reducing strain levels was a reactive post fixture fabrication process. We quickly recognized that the “reactionary” process was neither efficient nor were we capable on knowing the lowest achievable strain levels. Our engineering team came up with visual tools utilized during design to easily identify areas of excessive probe force, though still not enough data was generated to identify the lowest possible strain. Finite Element Analysis software models the PCBA and test fixture and applies the pressures from test probes and board supports and indicates the micro strain level applied to the PCBA. Using the FEA software during our design process allows our engineers to modify fixture designs to attain the lowest possible micro strain before fabrication begins.
