Calibration of materials
Material modeling and model calibration ( calibration of material ) is an important part of the finite element analysis of a structure whose accuracy has a great impact on the accuracy and error of the analysis results. The information obtained from the results of experimental tests is not always usable in finite element software. Finite element software (FEM) such as Abaqus software has a good ability to model different materials. However, many models are still not usable in the graphical software environment. Due to the ability to solve nonlinear in this software, it has been used for a long time in various industries such as the tire industry.
Calibration of material in Tire industry
The acceptance and use of material models related to the tire industry have led to the growth and development of more and more up-to-date elastomer models and reinforced structures in this software. Nonlinear behaviors of elastomers include nonlinear elasticity (hyperelasticity), damage (Molins effect), and viscoelastic behavior, commonly seen as hysteresis rings. It may be necessary to analyze the temperature-mechanical coupling, in which case there are some models of ready-to-use thermomechanical materials, and if there is no model, it is possible to develop the model by the user using the subroutine tool.
Medicine and Medical Engineering
Another industry in which material models are important is medicine and medical engineering. An industry in which the design and production of devices try to return part of the ability to patients or be used in this field. The main material models used in this industry are related to the material model of body tissue, muscle, cartilage, bone, and things like that. Much research has been done to determine the mathematical equations of these materials. Many of these materials are now available in Abaqus and LS-Dyna software.
Micro and nanoscale modeling
Another area of research currently underway is the modeling of materials according to their arrangement and structure at the molecular and nanoscales. In this regard, the powerful BIOVIA software is mostly used. Recently, modeling of composite and metal materials on a micro-scale has been considered. Modeling and analysis of failure of these materials on a micro-scale can be performed in different ways in Abacus software. For ease of simulation, a number of plugins have been developed for this purpose by various individuals and companies.
Calibration of material models
Working with any of the material models requires defining the material parameters that are obtained from the results of experimental tests. This is challenging when the behavior of the material is nonlinear. The company has the ability to calibrate these materials using different software. The information obtained from the calibration of materials can be used in a variety of engineering software such as Ansys, Abaqus, and LS Dyna.
