The beam is a specific structure commonly used in engineering. The beam can be made as an independent beam or can be combined with other structures such as plate, shell, or concrete solid structure to form an integral beam or multi-layer frame.

Due to the wide application of beams, the…

Modern electromagnetic research has penetrated various fields. In recent years, with the rapid development of new technologies such as 5G, electric vehicles, and IoT, the role of electromagnetic analysis has become more and more important. Electromagnetics simulation has been widely and successfully applied to many aspects of electromagnetic performance prediction…

With the development of computer graphics, hardware, and 3D printing technology, graphic rendering and its file format based on surface triangle mesh have become more and more popular. In finite element analysis (FEA), engineers sometimes get geometry files based on triangle meshes (such as STL files, etc.) and perform subsequent…

Curve fitting is a numerical process often used in data analysis. Its essence is to apply a certain model (or called a function or a set of functions) to fit a series of discrete data into a smooth curve or surface, and numerically solve the corresponding parameters, thereby obtaining the…

When a finite element analysis model contains hyperelastic materials, engineers usually have little substantial data to help get the results. Sometimes a lucky engineer will have some tension or compression stress-strain test data, or simple shear test data. Processing and applying these data is a critical step to analyze the…

The core loss of magnetic components plays an important role in engineering practices. Particularly at high-frequency conditions, the loss of magnetic components accounts for a large proportion of the energy loss of the whole unit. Most manufacturers provide the core loss curve in the product manuals. The core loss also…

In previous articles, we have introduced Arruda-Boyce, neo-Hookean, Mooney-Rivlin, Yeoh, Gent, Blatz-Ko and other hyperelastic models that often used in nonlinear finite element analysis. Now we will be discussing a special and widely applied hyperelastic model: Ogden. A versatile model that can be used for rubber, polymer, and biological tissues…

We have introduced the hyperelastic models commonly used in finite element analysis such as Arruda-Boyce, neo-Hookean, Mooney-Rivlin, Yeoh, and Gent. In this article, we will be discussing a very special hyper-elastic model: Blatz-Ko. The most hyperelastic models are mainly designed for incompressible materials, while Blatz-Ko is very suitable for modeling…

In previous articles, we introduced Arruda-Boyce, neo-Hookean, Mooney-Rivlin, and Yeoh hyperelastic models. Today, let’s discuss another well-known hyperelastic model: Gent. A phenomenological model of rubber elasticity that is based on the concept of limiting chain extensibility. In this model, a simple mathematical form is used to describe the nonlinear constitutive…

Previously, we discussed the Arruda-Boyce, neo-Hookean, and Mooney-Rivlin models. In this article, we will be talking about the Yeoh hyperelastic model, also called the Reduced Polynomial model. …
