Prediction of the thermomechanical behavior of particle reinforced shape memory polymers

Shape memory polymers (SMPs) have drawn wide attention because they can recover from a deformed shape to their original shape by a certain external stimulus. However, Low modulus and recovery stress limit the application and development of SMPs. It is imperative to find an approach to improve or reinforce these mechanical properties of SMPs. In the present study, the mechanical properties and shape memory effect of spherical particle reinforced shape memory polymer composite (SMPC) are studied numerically through a representative volume element created by using the random sequential adsorption algorithm. The linear viscoelastic model is used to describe the thermomechanical behavior of the SMP matrix while the fillers are regarded as linear elastic glass beads. From our study, we find the elastic modulus and recovery stress are increased considerably by adding 15% volume fraction glass beads into the SMP. Furthermore, it is observed that filling particles slightly deteriorates the shape fixity ratio, however, hardly changes the effective shape recovery ratio for dilute inclusion cases. Our research demonstrates the feasibility of using glass beads to adjust the modulus and recovery stress of SMPs without dramatically affect the shape memory effects. We hope our findings would provide researchers with guides in designing and optimizing SMPC applications. POLYM. COMPOS., 00:000-000, 2017. V C

“…The rubber matrix was modeled as an incompressible Mooney‐Rivlin hyperelastic solid , and the strain energy density U of the rubber matrix took the form as

U = C_{10} true(I_{1} - 3 true) + C_{01} true(I_{2} - 3 true)

I_{1} = λ_{1}^{2} + λ_{2}^{2} + λ_{3}^{2}, I_{2} = λ_{1}^{- 2} + λ_{2}^{- 2} + λ_{3}^{- 2}

A computational model has been established for analyzing the interphase damage of short fiber reinforced rubber composites (SFRCs) under transverse static and fatigue tensile loads. A cohesive zone model was integrated with a stress-based fatigue damage model to simulate the damage initiation and propagation. To obtain the damage model parameters and validate the methodology, some tests of SFRCs under static and fatigue tensile loads were conducted. The simulation results agree well with the experimental data. It is observed that under static loads, the damage of SFRCs is dominated by the interphase damage before the strain reaches 38.04%. Under fatigue loads, the speed of damage propagation increases exponentially with cyclic numbers. Once the crack in the interphase is initiated, it extends to almost the entire interphase after several cycles because of the stress concentration near the crack tip. It is found that a good initial adhesion status of the interphase can effectively improve the antifatigue performance of SFRCs.

“…AH is also used to predict the effective properties of composites under finite strains [7][8][9][10][11]. Due to the nonlinearity of the problem of mechanics at finite deformations [12][13][14][15], the AH method encounters certain difficulties in implementation. The complexity of this method is justified by the possibility of obtaining a more accurate approximation of the desired solution compared to the theory using only effective properties.…”

A coupled micro- and macroscopic modeling of an incompressible layered composite material under finite deformations is performed based on the asymptotic homogenization method and universal semi-linear models. The deformation diagrams of the periodicity cell are calculated. A method for searching for effective transversally isotropic properties of LCM based on the obtained diagrams is considered. Cylindrical bending of an LCM plate is simulated using the model of a transversally isotropic medium. The microstresses in the periodicity cell are calculated based on the homogenized stresses.
