Wood warping costs the wood industry in the U.S. millions of dollars per year. [citation needed] Straight wood boards that leave a cutting facility sometimes arrive at the store yard warped. Although wood warping has been studied for years, the warping control model for manufacturing composite wood hasn't been updated for about 40 years ...
Affected objects may show surface irregularities such as small cracks and fractures, blisters or pitting. Over time, the material slowly expands, cracking, buckling and warping in an irreversible process that makes the object exceedingly brittle and prone to fracture, and can eventually shatter the object, destroying it altogether. Due to the ...
Highly decorative wood-shingle siding on a house in Clatskanie, Oregon, U.S. Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable ...
The primary purpose of blocking is to brace longer frame members to help resist buckling under vertical compression. The intervals for the blocks are specified in the building code or as calculated by a structural engineer.
Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. . Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capac
Between 1993 and 1997, design and process solutions were developed to improve the functionality and durability of the product. In 1997, one vinyl siding manufacturer launched the first full-scale commercialization of insulated vinyl siding. Between 1998 and 2003, most other vinyl siding manufacturers launched their own brands of insulated siding.
Thicker grades of vinyl siding may, according to some, exhibit more resistance to the most common complaint about vinyl siding – its tendency to crack in very cold weather when it is struck or bumped by a hard object while others feel that a thinner product may allow more 'flex before cracking' and is a subject of debate. However, at "This ...
This is because under compression, most materials will experience trivial (lattice mismatch) and non-trivial (buckling) events before plastic deformation or fracture occur. Hence the intermediate processes that occur to the material under uniaxial compression before the incidence of plastic deformation make the compressive test fraught with ...
