This protocol describes the study of the quasi-static compression performance of corrugated tapered tubes using finite element simulations. The influence of the thickness gradient on the compression performance was investigated. The results show that proper thickness gradient design can change the deformation mode and significantly improve the energy absorption performance of the tubes.

In vivo cine intravascular ultrasound images show the coronary cross-sectional movement corresponding to different pressure loading conditions. Based on a finite element model, an iterative scheme was employed to determine the patient-specific mechanical properties of coronary arteries in vivo by matching coronary motion from the computational model and medical images.

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.ElementsElements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Periodic Classification of the Elements

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

The model reformulates differential equations as boundary integral equations, shifting the calculation from relationships defined throughout a volume to conditions expressed along its boundary. Researchers then represent that boundary with discrete elements and solve for unknown quantities, such as displacement, pressure, or field intensity. This formulation links boundary interactions directly to the system response.
Reducing the dimensionality can make simulations more manageable because the model does not require representation of the entire volume in the same way. This advantage is especially relevant for large or unbounded domains, where describing all interior regions may be difficult. The resulting formulation can simplify analysis while retaining the effects of boundary conditions on behavior.
Boundary conditions determine how the system is constrained or influenced at its interfaces, so they strongly affect the calculated response. Changes in those conditions can alter quantities such as displacement, pressure, or field intensity. Comparing alternative boundary conditions allows researchers to examine how interactions at interfaces produce different overall behaviors without changing the underlying modeling framework.
A Boundary Element Model concentrates its representation on the system boundary, whereas a volume-based representation describes the domain throughout its interior. This distinction changes where the computational problem is discretized and can reduce the dimensionality of the analysis. The boundary-focused approach is therefore useful when boundary interactions and conditions are central to interpreting the system response.
Construction begins by identifying the governing conditions and expressing the associated differential equations as boundary integral equations. The relevant boundary is then divided into discrete elements, and the unknown boundary quantities are formulated for solution. After solving for values such as displacement, pressure, or field intensity, researchers use those results to evaluate the predicted system behavior.
Researchers may choose this approach when the study focuses on how boundary or interface conditions affect a system, particularly in large or unbounded domains. The model supports prediction of system responses under competing conditions, making it useful for comparing behavioral outcomes and examining which interactions at interfaces account for observed differences.
A model can provide predicted values for boundary-related quantities, including displacement, pressure, or field intensity, together with the resulting system response. These outputs help researchers compare conditions and assess how interface interactions influence behavior. In behavioral and physical research, the value lies not only in prediction but also in connecting altered boundary conditions with changes in the overall outcome.
