Abstract

An existing robust three dimensional finite element based on the strain approach is presented. This element is implemented, for the first time in the commercial computer code ABAQUS, by using the subroutine (UEL), for the static and dynamic analysis of isotropic plates, whatever thin or thick. It is Baptised SBH8 (Strain Based Hexahedral with 8 nodes) and has the advantage to overcome the problems involved in numerical locking, when the thickness of the plate tends towards the smallest values. The implementation is justified by the capacities broader than offers this code, especially, in the free frequencies computation. The results obtained by the present element are better than those given by elements used by ABAQUS code and the other elements found in the literature, having the same number of nodes.

基于实体应变的有限元在ABAQUS中实现，用于板的静、动分析

提出了一种基于应变法的鲁棒三维有限元方法。这个元素第一次在商用计算机代码ABAQUS中实现，通过使用子程序(UEL)，用于各向同性板的静态和动态分析，无论薄或厚。它被洗礼为shbh8(8节点应变六面体)，并且具有克服数值锁定所涉及的问题的优势，当板的厚度趋于最小值时。实现的能力比提供的代码更大，特别是在自由频率计算方面。在节点数相同的情况下，本文单元的计算结果优于ABAQUS代码中使用的单元和文献中发现的其他单元。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
