Plastic Film Dragging

The dynamics of flexible bodies as they interactthrough contact with other bodies

<h5>Plastic Film Dragging</h5>
Plastic Film Dragging

RecurDyn offers unparalleled performance when solving the dynamics of flexible bodies as they interactthrough contact with other bodies. In this example, these features were tested by simulating the motion of a very thin plastic film (32µm) being dragged by two rollers. The film is connected to a tensioner and pulled by two rollers, which fold the film in the first step of a forming process.

The film was meshed using shell elements from RecurDyn’s proprietary Full Flex technology. The position of the film is controlled only by contacts (the connection with the tensioner being the only exception): flexible-to-rigid body contacts were used to represent the contacts with the rollers, while flexible-to-flexible contact was used to represent the film’s contact with itself. The model was used to evaluate the dynamic behavior of the film during the forming process, and to evaluate the stresses caused by the process.

CASE STUDY

Improving the performance of shaped charges and passive ballistic protections

CAE models evaluated using two commercial solvers

In this technical article, the authors discuss the development of CAE models for simulating the behavior of shaped charges, devices used in various industrial sectors, against two types of target – a monolithic steel target and a multi-layer steel-ceramic target – in order to better understand the physics of penetration.
