FEA model types

Viscoelastic finite element analysis employs a continuum-based linear material model, featuring a combination of elastic and viscous properties. This type of FEA model analysis allows for the consideration of both temperature and strain-rate dependencies in the mechanical response. It is specifically applied in scenarios involving small strain problems, offering a detailed understanding of material behavior under conditions where the impact of deformation is limited.

Electroplastic finite element analysis is a continuum-based material model that incorporates both elastic and plastic characteristics, allowing for the representation of permanent deformation and nonlinear behavior in adhesives. This model accurately captures the response under various loading conditions such as tensile, compression, and shear. Depending on the calibration, it can also account for strain rate and temperature effects. Pressure-sensitive elastoplastic models are frequently employed for polymers and adhesives, ensuring a comprehensive simulation of their behavior in diverse mechanical scenarios.

Finite strain is a continuum-based nonlinear material model that uses parallel networks of non-linear springs and dashpots to simulate the mechanical response of adhesives. The non-linear elastic behavior of the springs is determined by a strain energy density function, often characterized by hyper-elasticity. This model is typically utilized to represent adhesives undergoing substantial deformations with nonlinear viscous behavior. It accommodates mechanical responses under tension, compression, and shear. Depending on experimental inputs, temperature, strain rate, permanent set, and relaxation effects can be incorporated, offering a comprehensive representation of the adhesive's behavior under varying conditions.

A cohesive zone FEA model is a fracture mechanics-based material model designed for simulating crack separation within a bond line. This model incorporates traction-separation laws for mode I, mode II, and mode III fractures, with mixed mode behavior calibrated using experimental data. Its application is particularly valuable in predicting cohesive failures within adhesive bonds.
