Two workflows for the buckling analysis of a structure subject to gravity in Ansys

The Eigenvalue Buckling analysis in Workbench takes the results of a Static Structural analysis and calculates the load multiplier that would cause a structural buckling. If in the Static Structural analysis, loads and gravity are applied together to take into account the self-weight of the structure, then the buckling multiplier would also ‘multiply’ the gravity, … Continue reading Two workflows for the buckling analysis of a structure subject to gravity in Ansys

Layered Composite Modeling using Ansys ACP – A Wind Turbine Blade

A wind turbine blade is a long, hollow structural component made of composite material. Due to its slender nature, it is important to conduct a buckling design test to prevent such failure in service. This post illustrates how to use Ansys ACP to set up composite materials and apply them to wind turbine blade buckling … Continue reading Layered Composite Modeling using Ansys ACP – A Wind Turbine Blade

Nonlinear buckling analysis: considering both large deformation and material nonlinearity

In this post, we are going to do a nonlinear buckling analysis for a thin arch shell under uniformly distributed pressure. The configuration of the arch shell is as follows During the analysis, a linear buckling analysis will be conducted first to obtain the 1st-order eigenvalue (i.e. the linear buckling load) and eigenmode (i.e. buckling … Continue reading Nonlinear buckling analysis: considering both large deformation and material nonlinearity
