Linear Static Stress Analysis
Nonlinear Static Stress Analysis
Applicable for small deformations and infinitesmall strains. Nonlinearities are not present. This method provides fast and reasonably accurate solutions for a variety of structural problems.
Material and geometrical nonlinearities are accounted. This type of analysis is applicable for large deformations and plasticity. Also, simulations involving sliding contact fall into this category.
Steady State Dynamic Analysis
Modal analysis determines the dynamic signature of the structure by calculating the mode shapes and the natural frequencies that pair with those modes. It is the first step of any linear dynamic response analysis.
Structure’s response to Sinusoidal or Random vibration excitation extracted. Key results include acceleration and displacement responses, stresses and strains as a function of loading frequency. Most industrial vibration tests fall into this category.
Transient Dynamic Analysis
Explicit Dynamic Analysis
Structure’s response to a transient excitation extracted. Key results include acceleration and displacement responses, stresses and strains as a function of time. Shock pulses fall into this category.
This type of analysis is applicable for highly nonlinear and short duration events, such as crash simulations, drop tests, projectile impact, large plasticity, etc.
Creep and Viscoelasticity
Steady state or transient thermal simulations can predict temperature distribution or thermally induced stress and strains on the structure of interest.
Creep is a rate dependent material nonlinearity in which the material continues to deform under constant load. Loss of preload on polymer structures is a good example of this type of analysis.
