It can be used to describe an unintended collision or effect that occurs unexpectedly.
Example: "The accidental impact of the vehicle caused significant damage to the property."
Alternatives: "unintentional collision" or "unexpected effect".
(Bicycle helmets, by contrast, are designed to withstand just one major, accidental impact).
The perforation test covered impact kinetic energies from 21 J to 131 J, the equivalent range observed in a fall, an accidental impact or a bike accident.
Examples of loading of this type are the common three-point bend test used to determine the strength properties and failure modes, as well as accidental impact problems.
The formulae relating the material properties and heat input parameter should be, therefore, derived for the design purpose considering the accidental impact loading.
The results have a direct application in predicting the ability of sandwich structures to withstand localized loading such as from accidental impact.
The accidental impact of a vehicle against a supporting structure represents a handicap in modeling the imposed loads for a building.
Because accidental impacts are difficult to avoid, robust and reliable inspection methods to detect impact damage are required.
The installation of bumpers with enlarged travel reduces the probability of the accidental impacts and effectively trims the excessive deflections in an emergency.
Most people who post on Accidental Impacts were involved in fatal car crashes, but there are also cases of guns going off when they shouldn't have, of boating mishaps, and of momentarily neglected babies.
Green learned about Accidental Impacts from a therapist, who told her, at the end of their first session, "I'm sorry, but I don't have the resources to deal with this".
The blast-resistant capacities of UHSC and RPC were experimentally evaluated to determine the possibility of using UHSC and RPC in concrete structures susceptible to terrorist attacks or accidental impacts.
