The following symbols are used in this chapter. The section number in parentheses after
definition of a symbol refers to the section or figure number where the symbol first appears or …

This paper presents a novel methodology for detecting collisions of cylindrically shaped rigid
bodies moving in three dimensions. This algorithm uses line geometry and dual number …

Structural dynamics is a foundational topic for structural engineers. As commercial software
dominates the practice of engineering, it is more important than ever for engineers to …

DYCAST is a nonlinear structural dynamic finite element computer code developed for crash
simulation. The element library contains stringers, beams, membrane skin triangles, plate …

The results of an impact on a structure are always fascinating and it must be to the general
betterment of mankind that engineers and scientists have turned their attention to the …

Experimental modal analyses of civil engineering structures are performed for various
reasons. One is to assess the condition of the structure. Another is to verify the behaviour of …

Severe damage to dwellings and other types of structures can be caused by the impact of a
moving, or falling, object in the extreme events of rockfalls, landslides, severe windstorms …

Even if not explicitly considered in most structural design codes, nor studied in-depth in past
literature, reports from all over the world seem to indicate that accidental dropping of large …
