Effect of Rate of Loading and Duration of Load on Properties of Particleboard.
Abstract
Two conditions of loading which must be investigated to arrive at allowable working stresses for particleboard are (1) changes in rate of applying the load and (2) the duration of load to failure for materials under a constant load. This report presents the results of a study of the effects of rate of loading in bending tension, and shear and of duration of load in tension on the properties of several commercial particleboards and one laboratory-made board. Regression analysis of data for particleboards under constant stress levels in tension indicated that duration of load to failure increased tenfold for each 8.3 percent decrease in stress, when stress is expressed as a percent of static strength. This agrees with other published particleboard data when the same method of analysis is used.
