# Advanced Properties of Sinkage and Shearing

From the advance properties, you can choose different properties for longitudinal and lateral directions.

## Description

The soil link interaction model is based on Bekker, Janosi, and McKyes approaches. The basic properties are described in Basic Soil Properties and Basic Properties of Sinkage and Shearing. This section explains different plastic properties at each contact point of a track link. All data in this section should be in the non-dimensional form. The non-dimensional data is converted to dimensional data based on the input of Basic Soil Properties and Basic Properties of Sinkage and Shearing.

## Parameters

CJ1
Cohesion, C of the Janosi approach, for the longitudinal direction.
The dimensional value: CJ1=Cbasic*CJ1.
CJ2
Cohesion, C of the Janosi approach, for the lateral direction.
The dimensional value: CJ2=Cbasic*CJ2.
PHIJ1
Angle of internal friction, Φ, of Janosi, for the longitudinal direction.
The dimensional value: PHIJ1=PHIbasic*PHIJ1.
PHIJ2
Angle of internal friction, Φ, of Janosi, for the lateral direction.
The dimensional value: PHIJ2=PHIbasic*PHIJ2.
KJ1
k of Janosi, for the longitudinal direction.
The dimensional value: KJ1=KJbasic*KJ1.
KJ2

RJ1
r of the modified Janosi, for the longitudinal direction.
The dimensional value: RJ1=RJbasic*RJ1.
RJ2

If RJ2<0, then RJ2= |RJ2|.
It is recommended that in the lateral direction, set RJ2=-1.
