Introduction,cially if experiments are expensive, time consuming, or difficult to perform. Static analysis, plastic deformations, optimization, and free vibrations are fields sufficiently well explored, and now possess efficient numerical procedures implemented in commercial software. But the case of moving loadMIME 发表于 2025-3-25 08:03:20
Analytical Solutions,imited, must be described in the entire spatial domain of the structure, for example 0≤ . ≤ l. Multiplication of the force by the Dirac delta function .(.) leads to such an effect. Then we have the load terms .(. − ..). or .(. − ..).d../d.. described in the domain of the problem.

Classical Numerical Methods of Time Integration,previously published methods were implemented. Then, more effective solutions were sought. New methods were created incomparably faster. With the increasing computational power of computers, new and more complex issues were studied: the problems of geometric and material non-linearities in the dynam跟随 发表于 2025-3-26 02:00:04

Examples of Applications,tructures we always ask questions as to what geometry and what values of the material data are appropriate to pass from the physical model of the structure to the numerical one. Real shapes are usually complex and we try to simplify them, replacing curves with straight lines, non-uniformly distributmastoid-bone 发表于 2025-3-26 19:46:02
