Numerical investigation of hot bulk forming processes with respect to the resulting residual stress distribution

Abstract: The cost‐ and time‐efficient design of today's manufacturing processes is closely linked to numerical simulations. By developing and applying suitable simulation models, component properties can be specifically predicted and, if necessary, modified according to the customer's specifications. One important aspect of this is the adjustment towards advantageous residual stress profiles, for example to increase service life or wear resistance. Hot forming processes offer the advantage of the interaction of thermal… Show more

“…Due to the position, stress component 𝜎 22 resembles the tangential stress in the examined point. Qualitatively, there is good accordance achieved compared to a previously investigated two-dimensional boundary value problem regarding both cooling strategies [18,27]. A detailed discussion of the stress evolution regarding cooling in water that leads to tensile stresses in P1 in the final state (cf.…”

“…The stresses are weakened when the phase transformation front, which progresses from left to right through the geometry [18, 19], reaches the bulk material. In contrast to the two‐dimensional analysis carried out in [27], the stress does not change its sign, that is, the stress value is reduced but remains compressive. Thus, in the final state, compressive stresses are present in particularly in the spray exposed region around P1 (cf.…”
