The effect of texture in modeling deformation processes of bcc steel sheets

• Evaluation the value of damage based on change of the Young's modulus.
• Measurements of Young's modulus using changes on the natural frequency.
• ODF is responsible for the anisotropy of the properties.
• Combinations of averaging the direction cosines of crystals, obtained from the ODF.
• Relationship between texture and anisotropy of the damage.

In textured polycrystals, combinations of averaging the direction cosines of crystals (CADCC) were found which define interdependences between the crystallographic texture and the anisotropy of the kinetic and elastic properties of a steel sheet. It was shown that in case of bcc materials, three of these parameters exist which can be calculated using the orientation distribution function (ODF).Based on the ODF, the CADCC were calculated for dual-phase steel DP600 sheets before and after annealing at 220 °C and subsequent deformation by tension to 3%, 6% and 10%. Additionally, damage development was analyzed in this study.
