Shell elements are finite elements used in structural analysis to model thin-walled structures or components, such as plates, shells, and membranes. These elements are designed to capture the behavior of these structures, which have two dominant dimensions (length and width) and a relatively small thickness compared to the other dimensions. Shell elements are used to […]
Linear static analysis refers to a computational technique used in engineering and structural analysis to predict the response of a structure under applied loads or forces. It assumes linear relationships between applied loads and resulting displacements, as well as linear elastic material behavior within the structure. In linear static analysis, the governing equations of linear […]
Isotropic material properties refer to the characteristics of a material that are independent of direction. In other words, their mechanical and physical characteristics, such as elasticity, thermal expansion, and conductivity, are the same regardless of the direction in which they are measured. Isotropic materials exhibit the same response to stress, strain, and other external factors, […]
Linear static analysis has numerous practical applications across various engineering disciplines. Here are some common practical examples mentioned: Structural Analysis: Linear static analysis is widely employed in structural engineering to evaluate the behavior of various structures, including buildings, bridges, towers, and other architectural elements. It helps determine the stresses, deformations, and displacement patterns under different […]

When deciding the types of meshing in ANSYS, several criteria should be considered to ensure an appropriate mesh for accurate and efficient analysis. The key criteria include: Geometry: Consider the complexity and shape of the geometry. For simple geometries, structured meshing can be suitable, while for complex and irregular geometries, unstructured meshing may be more […]
Element quality refers to the measure of how well an element represents the physical shape or behavior of the structure or system being analyzed. It provides an indication of the accuracy and reliability of the numerical results obtained from the finite element analysis (FEA). ANSYS uses various metrics to evaluate the element quality. Some commonly […]
