Slow crack growth (SCG) is a time-dependent quasi-brittle type of failure that polyethylene
(PE) materials exhibit under low stress levels. The interplay between the crack and its plastic …

A machine learning based model is proposed to describe the temperature and strain rate
dependent response of polypropylene. A hybrid modeling approach is taken by combining …

The low recovery stress has limited utilizing shape-memory polymers (SMPs) as actuators.
In this work, we demonstrate that the resultant recovery stress of amorphous SMPs can be …

Hard-magnetic soft materials are a class of magneto-active polymers (MAPs) where the
fillers are composed of hard-magnetic (magnetised) particles. These materials present …

The double yield (DY) phenomenon observed in a wide variety of semi-crystalline polymers
(SCP) adds difficulties in the material characterization. In this paper, a constitutive model …

In this paper, a recently proposed finite strain visco-elastic visco-plastic (three-dimensional)
constitutive model is extended to predict the nonlinear response of amorphous polymers …

Most of the stress–strain relationships of thermoplastic polymers for aeronautical composites
tend to be nonlinear and sensitive to strain rate and temperature, so accurate constitutive …

Additive manufacturing enables the production of complex structures not possible with
traditional methods. Such structures are attractive for use in various engineering …

Soft materials that can deform under external stimuli offer great opportunities for the
development of new structural applications such as sensor-actuator systems, soft robots or …

A mesoscale numerical model based on shear transformation zone (STZ) theory is
implemented in a commercial finite element software. The model is designed to predict the …
