Özet
General physical properties, bending stress, modulus of elasticity, compressive strength, shearing stress, and specific shearing energy were determined for safflower (Carthamus tinctorius L.) stalks. Test specimens were taken front two locations of the stalk: front the bottom and front the top region. Experiments were conducted in five different moisture contents of stalk. The bending stress decreased with increasing moisture content. The average bending stress value varied between 54.02 and 13.81 MPa. The modulus of elasticity in bending decreased with increases at the moisture content and the modulus of elasticity increased towards the top region. The average modulus of elasticity varied between 439.49 and 95.62 MPa. The modulus of tangent in compressing decreased as the moisture content increased. The average tangent modulus varied between 31.39 and 6.35 daNmm(-1). The shearing stress and the specific shearing energy increased with increasing moisture content. The maximum shearing stress and the specific shearing energy were 1.37 MPa and 94.64 mJmm(-2) respectively. Both the shearing stress and specific shearing energy were found to be higher in the bottom region of the stalk.
