“…This observation is a strong indicator that thinner tiles tend to have a higher residual stress when compared with similar sized thicker tiles. This trend is in agreement with the previous study performed on simple flat square tiles made from pressureless sintered SiC material . There is also a size effect when curve fitting was carried out to the stress data points shown in Fig.…”

Residual stresses were measured on numerous multi-curved, ballistic tiles made from either silicon carbide or boron carbide. Residual stresses were measured at 155 locations to determine what affect parameters such as material, material processing, tile geometry, and manufacturer had on residual stress type and magnitude. 23% of data points had tensile residual stress. The highest residual stresses were measured in tiles with either the largest surface area or smallest plate thickness. Higher stresses were measured in silicon carbide tiles compared with boron carbide tiles. Residual stresses in tiles consolidated by hot pressing measured on average 10 MPa higher than those by pressureless sintering. *lwang@oakland.edu
