In this paper, the template will be developed from an assumed Stress Method, which its formulation is based on the Hellinger-Reissner principle developed according to Kang's study in 1986. The element stiffness is decomposed into a basic part that takes care of consistency and mix-ability, and a HO element stiffness part that takes care of stability (also known as rank sufficient) and accuracy. In the FE method, the HO stiffness is based on a displacement formulation, whereas the basis stiffness is method independent. To start, one should be familiar with the definition of a solid brick element. Solid brick element is three-dimensional finite elements that can model solid bodies and structures without any a priori geometric simplification.

翻译：在本文件中,模板将根据假定的应激反应方法制定,该方法的拟订依据了Kang1986年研究制定的《Hellinger-Reissner原则》,该要素的坚硬性被分解成一个基本部分,基本部分要注意一致性和混合性,而 HO 要素的坚硬性部分要注意稳定性(也称为等级足够)和准确性。在FE方法中, HO的僵硬性基于一种离位配方,而基础坚硬是独立的方法。首先,应当熟悉固砖元素的定义。固砖元素是三维的有限元素,可以在不事先进行几何简化的情况下模拟固态的体和结构。
