What is linear elastic finite element analysis?
The linear elastic FE analysis is an efficient modelling approach for simulating the mechanical behavior of bone tissue. From: Computational Modelling of Biomechanics and Biotribology in the Musculoskeletal System (Second Edition), 2021.
What is linear elastic method?
Linear elasticity is a mathematical model of how solid objects deform and become internally stressed due to prescribed loading conditions. It is a simplification of the more general nonlinear theory of elasticity and a branch of continuum mechanics.
What is linear elastic structure?
A linear elastic material is a mathematical model used to analyze the deformation of solid bodies. It is useful to compute the relation between the forces applied on the object and the corresponding change in shape. In other terms, it relates the stresses and the strains in the material.
What is H method in finite element method?
H-method. The h-method improves results by using a finer mesh of the same type of element. This method refers to decreasing the characteristic length (h) of elements, dividing each existing element into two or more elements without changing the type of elements used.
What is linear plastic material?
A term for thermoplastic optical materials; that is, those in which the polymer chains remain linear after heating and molding and which thus can be remolded again and again, unlike thermoset plastics, which cannot be remolded.
What is an isotropic elastic material?
A material is said to be isotropic if its properties do not vary with direction. Isotropic materials therefore have identical elastic modulus, Poisson’s ratio, coefficient of thermal expansion, thermal conductivity, etc. in all directions.
What is linear isotropic elastic?
What is H and P method?
h-method: This method increases the number of elements and hence decreases the element size while keeping the polynomial order of the constant. p-method: This method increases the polynomial order of the interpolation function while keeping the number of elements constant.
What are H and P versions of finite element method?
There are three versions of the finite element method. The classical h version, which achieves the accuracy by refining the mesh while using low degrees p of the elements, usually p = 1, 2. The p version keeps the mesh fixed, and the accuracy is achieved by increasing the degree p.
Is rubber linear elastic?
For many materials, linear elastic models do not accurately describe the observed material behaviour. The most common example of this kind of material is rubber, whose stress-strain relationship can be defined as non-linearly elastic, isotropic and incompressible.
Is steel linear elastic?
This means that steel is a nice material to model with linear elasticity, as long as you don’t reach strains (and stresses) that would cause yielding.
What is the difference between isotropic and anisotropic?
Isotropic refers to the properties of a material which is independent of the direction whereas anisotropic is direction-dependent. These two terms are used to explain the properties of the material in basic crystallography.
