Infinite Complanation for Semi-infinite Problem when Mass Concrete Hit by Cold Wave

Strategic Study of CAE 2002, Volume 4, Issue 7, Pages 33-39
Almost all the cracks in mass concrete are surface cracks. Full-section cracks and deep-level cracks are mainly developed from early surface cracks. This paper describes the characteristics of the surface cracks of mass concrete firstly. Then a semi-infinite plane model for surface temperature calculation is compared with infinite model. The temperature of surface zone in mass concrete under different boundaries is controlled by semi-infinite model, and is transferred to and calculated by an equivalent infinite model under certain conditions. If the temperature declining duration of air is no more than the critical time when the disturbed front perforates half-thickness of the infinite plate, it may be expressed as multi-line process approximately, and most importantly the temperature in surface zone of concrete can be calculated with the formula educed by infinite model. With 400 mm × 400 mm × 220 mm concrete specimens, the temperatures in surface zone are experimentally researched under outside environment, which has attested the method presented. It is also found that the new method to describe declining process of air temperature is more accurate than the method prevailing, and there does exist an opportunity to develop a physical model for the temperature process of mass concrete within a short period of time.

Transient analysis of thermoelastic contact problem of disk brakes

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 2, Pages 150-159 doi: 10.1007/s11465-013-0266-6
The main purpose of this study is to analyze the thermomechanical behavior of the dry contact between the brake disk and pads during the braking phase. The simulation strategy is based on computer code ANSYS11. The modeling of transient temperature in the disk is actually used to identify the factor of geometric design of the disk to install the ventilation system in vehicles. The thermal-structural analysis is then used with coupling to determine the deformation established and the Von Mises stresses in the disk, the contact pressure distribution in pads. The results are satisfactory compared to those found in the literature.

Hydrocele of the canal of Nuck — an old problem revisited
John Bunni, Mark Gillam, Ian Michael Pope
Frontiers of Medicine 2013, Volume 7, Issue 4, Pages 517-519 doi: 10.1007/s11684-013-0300-4
Herein the authors describe the case of a young woman presenting with a tender lump in her groin. Clinically the differential was of either a reactive lymph node or a femoral hernia. Ultrasound scan was urgently arranged and showed a cystic lesion. Surgical exploration was carried out and revealed this to be a hydrocele of the canal of Nuck. This was excised and the patient’s symptoms resolved and she was discharged home the following day. We explore the embryology, pathophysiology and management of this rare entity.
