Hearmon (1954), one of the first review of the creep data of wood to 1953 bodig Jayne (1982) and wrote the book that covers about the mechanics of materials, wood and wood. They approached the creep of wood from the flow (flow) point of view, such as the time between stress and stress of material from wood to conceal, the size of the creep strains depends upon a number of factors. The most important condition, including the position of the axis orthotropic wood compared to load the size and type of stress, rate of load duration load con - tent. Humidity and temperature, there are many beneficial situation, which is especially important การคืบ of wood: for example, the deflection of the wooden beams and other types. Load - carrying members of wood under the long time of load; reduced pressure between layers of members only due to creep relaxation results in loss of obligations. And creep of wood members Sustainable load less load constant best. In spite of the complexity of the wood, many too. The concepts used in the study of creep of metal used. And study in the wood is placed on the curve of the experience - mental information to get rule flow around. Because of the nature of the manufacturing process of composite wood. Relax could greatly affect the efficiency of mixed wood and creep (bodig, Jayne 1982). In contrast to the creep of metal form described in terms of the third stage of bodig Jayne considering consolidation and defor - data is composed of elastic parts For example, consider a strong and flexible. Speci - men want immediately applied load P at a time (Figure 18.12) deformation at a later time. TL used.
