High Rate Testing and Modeling of Polymers

Training
Outline [table id=5 /] Class Location: Veryst Engineering, 47A Kearney Road, Needham, MA 02494, USA [maxbutton id="4"] Introduction Predicting both the high and low strain rate response of different polymers can be difficult due to material non-linearities and sensitivity to the load environment. This class will demonstrate different experimental techniques for determining the true material response, and exercise suitable material models for capturing the material response in both slow rate and impact conditions. Prerequisites The training class is intended for people with some experience running finite element programs. The examples presented in class will use the commercial finite element program Abaqus. The material models presented in class are available for Abaqus, ANSYS, LS-DYNA, COMSOL, and MSC.Marc, and the course is applicable to all finite element codes. Learning Objectives By the…

Training Classes

Training Classes

topics
FEA Training Classes Advanced non-linear finite element user material modeling of polymers and other soft materials The complex response of polymers can be difficult to capture in FE simulations. The PolyUMod library provides some very useful tools to help with these simulations, but the key steps to accurate simulations can still be difficult to grasp at first. To overcome this problem we have developed a series of training classes to help all levels of FE users more accurately predict the non-linear response of different polymer types. The training classes are offered both online (web-based) and in-person (classroom-style), and cover the following topics: polymer mechanics, experimental testing, material model selection, and advanced finite element modeling techniques. The training classes are targeted to people with an interest in learning the state of the…

Finite Element Modeling

Finite Element Modeling

topics
Once the material model has been calibrated, the finite element model can be created and analyzed. There are many different challenges that need to be addressed when analyzing rubbers, thermoplastic, thermosets, or biomaterials. See the PolymerFEM.com website for online help.

Material Model Calibration

Material Model Calibration

topics
Selecting and calibrating a suitable material model can be very challenging. Most commercial FE codes do not have accurate native material models for many important polymer materials. The PolyUMod library enables accurate predictions of virtually all polymer materials. https://www.youtube.com/watch?v=aGrqMM6uMPQ

Experimental Testing

Experimental Testing

topics
Accurate FE simulations of any material requires accurate experimental data for material model selection and calibration. Different types of polymers should be tested in different ways in order to extract the characteristic experimental response using a small number of tests. See the Veryst web site for suggestions on suitable experimental test programs.

Why PolyUMod

Why PolyUMod

topics
In many important applications the material response is sufficiently non-linear that simple hyperelasticity or metal plasticity is not good enough. In these cases the PolyUMod library can be very useful since it contains a selection of the most advanced and accurate material models that are currently available. The PolyUMod library is easy to use and can give you a significant competitive advantage!
