Types of Structural Analysis:
Linear
- Linear stress and deflection analysis
- Static or Dynamic linear vibration analysis
- Failure analysis based on yielding
Non-Linear
- Non-linear stress and deflection analysis
- Non-linear vibration analysis
- Non-linear failure analysis based on fracture
Software :
- Mechanica (ptc.com) linear static and dynamic structural analysis using adaptive P elements for error control
- Adina (adina.com) Non-linear static and dynamic structural analysis including contact, material, and geometric structural non-linearities
In general the above analysis types address the 3 basic Engineering issues:
Will a part or assembly fail in service due to excessive deflection or to yielding or even fracture, and what practical design changes can be implemented to remedy such problems?
Will a part vibrate excessively or even resonate in service resulting in nuisance noise and ultimate fatigue failure, and what practical design changes can be implemented to remedy such problems?
Does a part have wasted material in areas of low stress, resulting in excessive cycle time and material costs, and what practical design changes can be implemented to remedy such problems.
