“…For PS model, the simulation accuracy may increase with a larger number of model parameters. However, it has been usual to use a term number of ≤ n 7 for PS in numerical practice for simplicity purose 46,47 , which may cause potential numerical errors. Resutls also indicate that the developed model is always numerically stable.…”

We developed an innovative material nonlinear viscoelastic model with physical mechanism and mathematical solution to improve existing ones. the relaxation modulus transits from the glassy stage to the rubbery stage through a time-dependent viscosity in a continuous spectrum considering the nonlinear strain hardening. Experimental results of differential solid materials including asphalt concrete, agarose gel, vaginal tissue, polymer, agar, bone, spider silk, and hydrogel demonstrate that the developed model is superior to generalized Maxwell model or Prony series for more accurate prediction outside of the range for data fitting while using much less model parameters. Numerical simulation results indicate that the new model has improved accuracy. It is stable numerically, and does not reduce computation speed. Therefore, the model may be used to simulate a broad range of viscoelastic solids for predicting experimental data and responses with improved accuracy.

“…Masad et al implemented the Schapery single integral model in the ABAQUS finite element software for asphalt binders and found that the FE results fit well with the experimental data of dynamic shear rheometer tests [12]. Al-Qadi et al obtained the parameters of the time-hardening model from creep test results and incorporated the data into a three-dimensional (3D) finite element model, it has been shown that rutting damage in HMA and shear creep strains at the edge of the tire imprint can be predicted [13].…”

“…Thus, the Findley model is a promising nonlinear model for HMA. Due to fewer parameters and a simpler modelling process, the time-hardening model has been frequently implemented in the commercial FE software ABAQUS as a build-in access [13,17,18]. Apart from the above models, we wonder whether the simplified multiple integral model could be employed to represent the nonlinear creep behaviour when neglecting massive workload.…”

“…Several thousand loads which were repeated in cyclic pattern have been employed to make permanent displacements. To reach this aim, UTM5 was used to perform dynamic creep test, the stress level of 450 kPa and a temperature of 50 ° C is considered as a constant variable in this research and sample loading is started up to 0.01 strain rate [17]. The diameters of the cylinders were 100 to 150 (mm) and the height of them is 60 (mm) [18].…”

In the recent decades, different kinds of fiber materials are used for improving the asphalt mixture performance. Meanwhile, different kinds of fiber are used excessively due to their desirable physical and chemical properties and their easier application. The main purpose of this research is to evaluate the characteristics of the asphalt mixture while using basalt fiber and glass fiber. In order to provide asphalt samples, these two types of fibers are used in different percentages. In this way, 42 samples (with different percentages of fiber and bitumen) were made using Marshal Hammer. In the next step, while constructing 63 asphalt samples using a gyratory device, then mix asphalt conventional tests include the determination of indirect tensile strength, moisture sensitivity test, and resilient modulus and creep tests performed. The results of this research indicate that using these two types of fibers increased the percentage of optimum bitumen and marshal resistance. At best, adding 0.1% glass fiber resulted in 13% increase in marshal resistance. Finally, ANFIS-GUI was used to estimate the experimental result and the feasibility of employing neural fuzzy network to predict the laboratory data have been evaluated.
