Shrinkage cracks in the wood
Shrinkage cracks occur as a result of evaporation or chemical conversion of water within the cell walls of the wood. These cracks are caused by volume changes in the affected cross-section. This is accompanied by a change in volume of the affected cross-section. Since the water loss in the outer area of the cross-section is faster than in the inner area, stresses occur that can lead to cracking of the cross-section.
Causes of shrinkage cracks in wood
Shrinkage cracks in wood are caused by a number of factors, including moisture, temperature and chemical changes in the wood. If wood is dried too quickly or if it loses moisture too quickly, this can lead to shrinkage cracks. Chemical changes in the wood can also cause it to develop shrinkage cracks.
Effects of shrinkage cracks
on timber cross-sections
Shrinkage cracks can cause wood to swell, shrink or crack. When the wood loses moisture, it becomes smaller and may crack or warp. If shrinkage cracks are not detected and repaired in time, this can lead to serious structural damage. Therefore, it is important to treat and prevent shrinkage cracks in time.
