Prediction of Soil Forces Acting on Concave Agricultural Discs
TLDR
In this article, a mathematical model is presented for predicting the soil forces acting on concave agricultural discs operating with both disc and tilt angles, based on the basis that the curved cutting and scrubbing zones of the disc can be transformed into equivalent plane cutting surfaces.About:

Integrated soil tillage force prediction models
TL;DR: In this article, the authors describe the integration of a series of models to predict the forces acting on a range of tillage tools from simple plane tines to mouldboard ploughs.
Dissertation
Soil compaction and soil tillage - studies in agricultural soil mechanics
TL;DR: In this article, a model for predicting the distribution of stress below tyres using readily available tyre parameters is proposed, with a more realistic approximation of the stress distribution at the soil surface, simulated stresses generally agreed well with measured stresses.

Performance of Free Rolling and Powered Tillage Discs
TL;DR: In this paper, the benefits of driven tillage disc by an external power compared to the conventional free rolling disc under controlled experimental conditions were evaluated in the soil dynamics laboratory of Faculty of Agricultural Engineering, Kasetsart University, Kamphaengsaen Campus, Thailand.

The effect of the disc setup angles and working depth on disc harrow working resistance
TL;DR: This model describes the components of the horizontal and vertical resistance as a function of design parameters and disc settings expressed by means of pressure area with 99.7% accuracy for the horizontal component and in 99.9% for the vertical component of the resistance.

Predicting the draught requirements of concave agricultural discs
TL;DR: In this article, the mean equivalent stress derived by distributing the draught force uniformly over the furrow cross-section is calculated using a set of non-dimensional factors in a two-term additive equation.
