Fracture resistance of HMA mixtures under mixed mode I/III loading at different subzero temperatures

Cryoenzymology: the use of fluid solvent mixtures at subzero temperatures for the study of biochemical reactions.

Why low temperatures? A reaction with a n activation energy of 60kJ/mol will be decreased in rate by 100-fold if the temperature is decreased from 20 to -30°C. Depending on the rate of the reaction at normal temperatures, a decrease of this type can have a number of valuable effects. (i) Reactions normally occurring in a few seconds or minutes may be sufficiently decreased in rate t o permit re...

The Prediction of Surface Tension of Ternary Mixtures at Different Temperatures Using Artificial Neural Networks

In this work, artificial neural network (ANN) has been employed to propose a practical model for predicting the surface tension of multi-component mixtures. In order to develop a reliable model based on the ANN, a comprehensive experimental data set including 15 ternary liquid mixtures at different temperatures was employed. These systems consist of 777 data points generally containing hydrocar...

Finite Element Model of Crack Growth under Mixed Mode Loading

In this paper, in order to predict the crack growth trajectory and to evaluate the SIF under mixed modes (I & II), one proposes a new finite element program for crack growth using the source code written in FORTRAN. The fin ite element mesh is generated using an advancing front method, where the generation of the background mesh and the construction of singular elements are also added to this d...

Finite Element Modeling of Crack Initiation Angle Under Mixed Mode (I/II) Fracture

Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...
