Titanium implants are commonly used in dental and other joint replacements and its several modifications have been taken place to improve the adhesion between bone and implant. Different chemical and physical modifications are generally applied to the titanium surface for improving interlocking between bone and implant materials. The present work has been investigated the shear strength stiffness and stress concentration between Representative Volume Element (RVE) model and coating material while the surface of the RVE model modified with different types of surface textures. The surface topology parameters resulted a significant increase in shear strength by 55% and 45% for straight texture and U-shape texture, respectively compared with plain surface. The stiffness reduced significantly by 18% for U-shape and but to 36% only for X-shape, when compared with plain surface. The stress concentration factor in biaxial case both dome shape and X-shape has 45%and 25% in U-shape lower than that of the plain surface. Therefore, this investigation predicted the interfacial shear strength properties generated for different surface topologies to determine the bonding behavior of the implant materials.
