Structures are always vulnerable to deformations, irrespective of the nature of loading they are exposed to. However, when structures undergo deformation that is large enough to change their shape, size, or orientation it triggers certain effects that can impact a system's response. These effects can be accounted for in Ansys Mechanical by turning ON Large Deflection. Parts that may require large deflection analysis can be found everywhere around us, from sporting goods to seals in our appliances to wind energy blades. In this video, we will be hands-on inside Ansys Mechanical showing how we solve a large deflection analysis and how it affects our analysis results. // INTERESTED IN MORE?
