Distortion in Thermal Field Around Inserted Thermocouples in Experimental Interfacial Studies, Part 4: End Effect
TL;DR: In this article, a parametric finite element analysis has been conducted to model the general case of a three-dimensional thermocouple installation inserted in a blind hole, where the variables considered in this study are the level of the heat flux in the measurement zone, as well as the thermal characteristics of the thermocourer wires, the filler material (cement), and the solid material in which the installation is placed.

Hybrid-Trefftz quadrilateral elements for thick plate analysis
TL;DR: In this paper, a family of thick plate quadrilateral elements is derived based on the hybrid-Trefftz formulation, where exact solutions of the governing equations are used inside the element together with independent displacements and rotations on the boundary of the element.
