## How do you avoid large displacement in Solidworks?

Notes

1. Create a nonlinear study to handle large strain and material nonlinearity.
2. The large displacement solution does not work with: Spot weld and bearing connectors. Beam mesh or mixed mesh that includes beams. Remote mass loads. Rigid bodies.

## When selecting the large displacement option solidworks simulation does what?

The large displacement solution assumes that the stiffness changes during loading so it applies the load in steps and updates the stiffness for each solution step. When Large displacement is selected in the Static dialog box, the static study is solved by stepping the load and updating the geometry.

## What is large displacement?

A large displacement solution takes more time and resources than the small displacement solution but gives more accurate results. The large displacement solution is needed when the acquired deformation alters the stiffness (ability of the structure to resist loads) significantly.

## What is displacement analysis in Solidworks?

When setting up an analysis in SOLIDWORKS Simulation, we typically think of applying forces or other loads and calculating the resulting stresses and displacements as our outputs. This is known as a Prescribed Displacement and is available under the External Loads drop-down.

## What is small displacement theory?

(B) Infinitesimal strain theory, also called small strain theory, small deformation theory, small displacement theory, or small displacement-gradient theory where strains and rotations are both small. In this case, the undeformed and deformed configurations of the body can be assumed identical.

## What is considered small strain?

The definition of small strain would work for not more than 10%. Otherwise the second order (which is ignored) will be dominate. Small strain – or small displacement – refers to the case where we assume that changes after a displacement is so small that the geometry is virtually unchanged.

## How do you show displacement in Solidworks?

To display this PropertyManager, run a static, nonlinear, dynamic study, or drop test study. Right-click Results and select Define Displacement Plot. Displacement results are available for nodes only.

## What is deformation scale in Solidworks simulation?

The deformation scale refers to the scale factor that the program uses to scale the deformed shape of the model. For example, a scale factor of 50 means that the largest deformation calculated by SimulationXpress is shown as 50% larger than the largest dimension of the smallest boundary box that surrounds the model.

## How does SolidWorks calculate the maximum displacement?

For all models, SolidWorks calculates the maximum displacement and compares that over the length of the model. If that ratio is greater than 10%, it will generate the message. For models containing Pin Connectors, SolidWorks verifies the relative rotation (θ) within each individual Pin Connector.

## What actually happens in the background of simulation to trigger Excessive displacement?

Fig. 1: Excessive Displacement Message What actually happens in the background of Simulation to trigger this message? For all models, SolidWorks calculates the maximum displacement and compares that over the length of the model. If that ratio is greater than 10%, it will generate the message.

## Why does large displacement make my study run longer?

The assumption that Large Displacement makes is that the stiffness changes during loading so it applies the load in steps and updates the stiffness for each solution step. This is why you will notice that running under this mode will make the study run a bit longer.

## What does large displacement mode do?

The assumption that Large Displacement makes is that the stiffness changes during loading so it applies the load in steps and updates the stiffness for each solution step. This is why you will notice that running under this mode will make the study run a bit longer.
