In this paper,fluidity onset analysis in FG thick-walled spherical tanks under concurrent pressure loading and heat gradient has been presented. Designing thick-walled spherical tanks under pressure as tanks holding fluids under heat loads with high heat gradients require new approaches. Under high internal pressure and high temperature, the tank enters the plastic stage in a part of its thickn...

It is often assumed that ingestion of microplastics by aquatic species leads to increased exposure to plastic additives. However, experimental data or model based evidence is lacking. Here we assess the potential of leaching of nonylphenol (NP) and bisphenol A (BPA) in the intestinal tracts of Arenicola marina (lugworm) and Gadus morhua (North Sea cod). We use a biodynamic model that allows cal...

This thesis examines interactive computer graphics and biomechanical engineering analysis as components in a computer simulation system for planning plastic surgeries. A new synthesis of plastic surgery planning techniques is proposed based on a task-level analysis of the problem. The medical goals, procedures, and current planning techniques for plastic surgery are reviewed, and from this a li...

Whereas the higher-order versions of the finite element method (p and hp-versions) are fairly well established as highly efficient methods for monitoring and controlling the discretization error in linear problems, little has been done to exploit their benefits in elasto-plastic structural analysis. In this paper, we discuss which aspects of incremental elasto-plastic finite element analysis ar...

Three methods of plastic embedding were assessed for their value in routine dermatopathology. The J B 4, Taab embedding, and Taab transmit techniques were compared for quality, convenience, and safety. The Taab transmit method was the most satisfactory method, being both rapid and simple. An additional advantage is that the resin can be removed and the immunoperoxidase technique carried out on ...
