This module is an extension of the original Boyce-Parks-Argon model (rate- and temperature- dependent).

This module represents the softening part taking place in a damage process given by a traction-separation law. Coupling between damage under tension and compression can be chosen. Different criteria of damage initiation (principal strain, pressure-dependent parabolic function, stored energy, dilatation density energy or plastic strain) and different types of softening (linear, bilinear, trilinear, superelliptic, exponential) are available.

This module represents the healing mechanism in a damage process given either by a classical traction-separation law or a rate-dependent visco-damage model. This healing model incorporates the effects of resting time (RT), loading rate and damage level (both instantaneous and accumulated) on the healing variable.

This module provides the behaviour of the so-called "Standard Linear Solid model" (under Kelvin representation) that consists of a Kelvin-Voigt module in series with a linear elastic spring.

This module combines a linear elastic spring with a slider element in series to provide rate-independent plastic behaviour.

This module admits any user-defined strain-hardening evolution in tabular form.

The continuum isotropic damage model is connected in series to a linear elastic module. In the sample picture, linear and superelliptic softening are illustrated under tension and compression.

This combined module provides the response ruled by the so-called Generalized Maxwell model, consisting of a linear elastic module connected in parallel to several parallel Maxwell branches. This approach is commonly used to incorporate the rate dependency effect on the material stiffness. Different viscosities were assigned to the dashpot of each Maxwell component to introduce different time scales.

This module is similar to the previous one except for the connection in series between the Maxwell branches and the linear elastic spring.

This module incorporates rate-independent plasticity into the Generalized Maxwell model.

This module is obtained as a result of adding in series the classical elasto-plastic module to a collection or parallel-conected Maxwell branches.

This module incorporates damage to the plastic-enriched version of the Generalized Maxwell model. The resultant module is a visco-elastic-plastic-damageable solid. By using a pressure-dependent yield criterion for the elasto-plastic component, this combined module makes it possible to describe asphaltic-based materials.

This module provides strain-rate dependency in stiffness and strength by combining non-linear visco-plasticity, the Generalized Maxwell model and energy-based damage. This combined module makes it possible to describe the response of polymers.

This module provides strain-rate dependency by combining liner-elastiticy, the non-linear Bergstrom-Boyce viscous dashpot and a rate-dependent version of the damage model derived from CDamage. This combined module makes it possible to describe the response of the asphalt matrix.

This advanded combined module integrates the thermal complementary module to achieve full thermo-mechanical coupling. With this thermal component, heat transfer analysis can be conducted by considering heat generated from dissipation energy of the mechanical part. Thermal softening effect under high strain rates can be captured accordingly. This module constitutive model captures the response of thermosets polymers such as Epoxy.

This advanced module combination describes the thermo-mechancial response of Semi-Crystalline Polymers (SCP) such as PA6, nylon 101 or PE. The crystalline phase is explicitely described as an equivalent elastoplastic response that is activated according to the yield kinetics. Apart from self-heating and thermal softening, this model captures very accurately the "Double Yield" phenomenon.

This module relies on a unified formulation to capture the thermo-mechanical response of a wide variety of polymers. It uses a single viscoplastic law integrating both amorphous and crystalline phases under non-isothermal conditions useful to model either thermoplastics or thermosets. Dependencies of temperature, strain rate and crystallinity on the material response can be studied with this module. Apart from its accurary and applicability range, this module needs only three crystalline-related parameters with clear interpretation from stress–strain curves. This unified model predicts the experimental results of polymers such as epoxy, PEEK, nylon 101, PA6 or LDPE.
