`ball.stress.full`

Syntax

Tensor Access

m = ball.stress.full(bp)

Get the full stress tensor arising from all contacts acting on the ball. The stress tensor is computed as:

σ_{i j}^{(ϕ)} = \frac{1}{V} \sum_{n_{c}} (x_{i}^{(c)} - x_{i}^{(ϕ)}) F_{j}^{(c, ϕ)}

$\sigma^{(\phi)}_{ij} = \frac{1}{V} \sum_{n_c}(x^{(c)}_i - x^{(\phi)}_i) F^{(c,\phi)}_j$

This tensor is returned as a matrix with dimension {2*2 in 2D; 3*3 in 3D}. Use ball.stress to access the symmetric part of the ball stress tensor.

Returns:	m - full stress matrix.
Arguments:	bp - ball pointer.
