Computer-Aided Design, 1984
Abstract Current use of the finite element method in engineering practice is considered. The increasing use of finite element analysis in a CAD environment and factors influencing it are discussed. The technological state of the art is briefly reviewed.

In this chapter, essentials of finite element analysis on musculoskeletal biomechanics are studied. For this reason, some fundamental types of finite elements, methodology, and difficulties of finite element analysis are considered. Also, some information on well-known general purpose finite element codes preferred in biomechanics and biomaterials ...

Computer-Aided Engineering Journal, 1985
The finite-element method is a powerful tool for computer analysis of the characteristics of complex structures and components. This paper presents the fundamental principles of finite-element analysis together with the reasons for its use, and makes a case for introducing finite-element analysis techniques more often and earlier in the design of ...

Statistical finite element analysis
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008A novel technique is introduced for tissue deformation and stress analysis. Compared to the conventional Finite Element method, this technique is orders of magnitude faster and yet still very accurate. The proposed technique uses preprocessed data obtained from FE analyses of a number of similar objects in a Statistical Shape Model framework as ...

What Is Finite Element Analysis?
Clinical Spine Surgery: A Spine Publication, 2020Finite element analysis is a computational technique to predict how different materials will react when a range of forces are applied. In the field of orthopedics, this technique has predominantly been used for implant design and testing. As the technology improves, increasing clinical applications are being developed, offering promise in the areas of ...

Finite element analysis of inelastic structures [PDF]
9th Structural Dynamics and Materials Conference, 1968 Differential stress-strain relationships are used to generate a system of simultaneous firstorder differential force-displacement equations which are integrated numerically to obtain the stresses, strains, and displacements in inelastic structures. For the biaxially stressed element, the concept of isotropic hardening and a generalized stress are used ...

Probabilistic finite element analysis of a craniofacial finite element model
Journal of Theoretical Biology, 2012We employed a probabilistic finite element analysis (FEA) method to determine how variability in material property values affects stress and strain values in a finite model of a Macaca fascicularis cranium. The material behavior of cortical bone varied in three ways: isotropic homogeneous, isotropic non-homogeneous, and orthotropic non-homogeneous. The

Unified finite element analysis
International Journal for Numerical Methods in Engineering, 1983AbstractA special matrix is introduced, the elements of which are zero or first‐order differential operators. This matrix is used to define a boundary value problem which covers a wide class of engineering applications. An equivalent variational formulation is found using an extension of the Gauss theorem.
