The phrase "accidental loading" is correct and usable in written English.
It can be used in contexts related to engineering, construction, or any field where unintended forces or loads are applied to a structure or system.
Example: "The bridge was designed to withstand significant stress, but the accidental loading during the storm caused unexpected damage."
Alternatives: "unintentional loading" or "inadvertent loading".
However, crack size, postulated accidental loading, mechanical and fracture parameters are often subjected to considerable scatter or uncertainty.
Additionally, design to resist failure from accidental loading, such as fire and explosion and boat impact, is recognised as being particularly important.
However, when a column is lost owing to accidental loading, these conditions change, and the forces are redistributed to the adjacent beams and columns.
It is especially important for the prevention of over-engineering and the reliable assessment of complex accidental loading, such as extreme bending due to loss of buoyancy of support, or abrupt ground movement.
In order to get efficient solutions, engineers have to size parts for which the mechanical behavior of the material is not elastic anymore, at least for accidental loading conditions.
However, poor quality products and uncontrolled factors such as accidental loading (for instance impact loading), design faults, construction defects, and lack of maintenance lead to structural failure at loads well below design level or at service life well before design lifetime.
The helideck structure must satisfy the safety requirements associated with various environmental and accidental loads.
A probabilistic sampling approach with numerical fire simulations was taken to determine the fire accidental load.
Therefore, there is no justification for the introduction of a separate accidental load case.
The acceptance criterion corresponding to accidental loads and environmental loads from NPD is that no leak should occur.
Tying resistance is an important joint property for maintaining structural integrity in frames in case of accidental loads.
