Spherical Cavity Expansion

In recent years, Spherical Cavity Expansion (SCE) theory has been extensively utilized to model dynamic deformation processes related to indentation and penetration problems in many fields. In this review, the SCE theory is introduced by explaining the different mathematical features of this theory, its solution, and a potential application to model the penetration of a rigid penetrator into a deformable target. First, a chronologically literature review of the most common models used to study this kind of penetration problems is introduced, focusing on the SCE theory. Then, the engineering model of penetration is presented using the SCE approach. The model is then compared and validated with some FE numerical simulations and with previous penetration results. It is concluded that this engineering model based on the SCE theory can be utilized to predict the projectile deceleration and penetration depth into the semi-infinite and finite targets impacted by rigid penetrators.

Because of the great advantages of savings for installation costs and areas of the ground, the ground source heat pump (GSHP) system combined with the ground-coupled heat exchanger with structural member is becoming more and more popular such as energy pile foundation etc.. However, the calculation method especially on the perspective of plate-type ground-coupled heat exchanger (PGHE) has not been established. This paper reports a study on a mathematical model developed to analyze the heat transfer of U-tube plate-type ground-coupled heat exchanger (UPGHE) which combined with structural member and an analytical solution is revealed. The results show that there are clear ‘heat submerge’ for the leg with lower temperature of UPGHE and it is more sensible to arrange one leg apart from another. The results also show that the spacing of pipes have obvious impact on the performance of UPGHE and the temperature difference between two legs have no important effect on the total performance of UPGHE.

AbstractThe target article uses a mathematical framework derived from Bayesian decision making to demonstrate suboptimal decision making but then attributes psychological reality to the framework components. Rahnev & Denison's (R&D) positive proposal thus risks ignoring plausible psychological theories that could implement complex perceptual decision making. We must be careful not to slide from success with an analytical tool to the reality of the tool components.
