...Zhen Liu; Xingyu Gu; Qiao Dong A rutting prediction method for semi-rigid pavement structures using accelerated loading tests and finite element analysis was proposed in this study. Firstly, dynamic modulus and creep tests of three pavement materials were performed by changing sizes...

... implemented in a finite element model to perform the calculations in the frequency domain. Results show that pavements made with bituminous mixtures containing CR added by dry process dissipate more energy with respect to the reference mixtures without CR.

... in measuring stabilizing pile deformation over time. In the process of pile construction, the hydration heat of cement raises the temperature of the pile, thus causing errors in pile strain monitoring. So, the effect of temperature on strain should be considered. A finite element model built on the basis...

... C76 standard. The finite element model of the three-edge bearing test was calibrated and validated using the experimental results from previous work by the authors. The linear and nonlinear behavior of the synthetic fiber-reinforced concrete material was characterized using the concrete damage...

Neural networks are trained using the data from a series of finite element analyses. An exponential equation is then fitted...

... measurements (longitudinal, transverse, and vertical strain) in the field, together with a pavement rutting survey and finite element simulation, were carried out in order to clarify the causes of rutting happening in Beijing heavy-duty expressways. First, the basic principal of a fiber Bragg grating sensor...

The purpose of this study is to determine what errors may arise from using nonideal specimen size or current-electrode configuration. The dc four-point resistivity test is simulated using a finite element...

.... A specimen made from ceramic with very low CTE/CTC was also tested so that the influence of the self TE/TC of extensometers could be accounted for, and therefore, the measured deformation of an AC specimen was properly adjusted. A finite element (FE) model was developed to simulate the thermal stresses...

Finite element techniques are used to demonstrate that a minimum ratio of crack depth to notch root radius of 0.5 is sufficient for a valid test in a ceramic. These calculations are confirmed by experiments on soda-lime glass specimens. tests ceramics...
