Fracture Initiation and Propagation in Fatigue Contact Loading of AA6082 Aluminium Alloy Angela Benedetti1,a, Pier Gabriele Molari1,b and Piero Morelli1,c 1 Department of Mechanical Engineering, v.le Risorgimento 2 - 40136 Bologna, Italy a angela.benedetti@mail.ing.unibo.it, bpiergabriele.molari@unibo.it, cpiero.morelli@mail.ing.unibo.it Keywords: contact mechanics, fatigue of materials, crack initiation, crack propagation, aluminium alloys.
No cracks have been observed at the centre of contact, neither on the surface, nor inside the material.
The surface of the material is characterized by an evident plastic deformation with a spherical curvature whose maximum depth, measured at the centre, is equal to 0.48 mm.
The geometry of the studied model is shown in Fig.5, where the spherical surface of an isotropic linear elastic material (1 - steel) is pressed on the flat top surface of a cylindrical multilinear elastic-plastic material (2 - AA6082).

Thermal decomposition characteristics of Mg (NO3)2·6H2O and MgCl2·6H2O composite as phase change material Qing Ding1,2, a, Xuegang Luo1,2, b, Xiaoyan Lin1,2 1School of Materials Science and Engineering, Southwest University of Science and Technology, Mianyang 621010, China 2Engineering Research Center for Biomass Materials, Ministry of Education, China a email: ddingqqing@gmail.com b lxg@swust.edu.cn Keywords: Mg (NO3)2·6H2O; MgCl2·6H2O; decomposition; dehydration; Abstract: The thermal decomposition characteristics of Mg (NO3)2·H2O and MgCl2·6H2O composite were studied by integrated thermal analysis.
Results show that there are five steps during the thermal decomposition of phase change material (PCM): the starting temperature of each step is 35.5 oC, 93 oC, 196 oC, 260 oC and 318 oC, respectively.
Introduction Phase change materials have attracted the intensive interest of researchers as they are employed in an increasing number of applications in recent years [1].
Most of thermal energy storage systems are based on the use of phase change materials with high storage capacity.
