Modelling of solid-phase sintering of hardmetal using a mesomechanics approach

Research on seismic stability of reinforced concrete frame structure based on numerical simulation

“…With the strong problem-solving ability, it has a good performance in the analysis of the large-scale complex structure. The commonly used finite element software include ANSYS [4] and ABAQUS, which have a wide application in industries such as civil engineering [15], meteorology [6] and metallurgy [8]. In the reinforced concrete frame structure, there are differences between reinforcement and concrete in performance.…”

Modelling and simulation of process-integrated powder coating by radial axial rolling of rings

“…Further, we define the so-called effective Kirchhoff stress tensor (cf. Mähler and Runesson [15])τ = τ − τ s I (18) with the sintering stress τ s and the drag stress R work-conjugate to the accumulated plastic strain:…”

“…Generally, the free surface energy due to porosity depends on the surface area of the pores and thereby on the relative density and on the pore shape. In order to formulate an expression for ψ p , we adopt the ideas of Mähler and Runesson [15]. They assume the pore to be of spherical shape and to remain spherical throughout the compaction.…”

“…The pressure sensitivity of the yield surface is restricted to positive values for the pressure p = −trτ /3 by using the McCauley brackets in (27). Considering (15) in connection with (26.1) and (28), it can be seen that a decrease of the relative density can be avoided in this way.…”

“…McMeeking and Kuhn [18]). In this regard, the definition of a rational thermodynamic force, the so-called sintering stress, that is responsible for a densification even in the absence of an external load has been proposed, e.g., by Mähler and Runesson [15].…”
