Detailed Description

template<size_t N>
class GMatElastoPlasticQPot::Cartesian2d::Smooth< N >

Array of material points with an elasto-plastic material model.

The response is defined by a potential energy landscape consisting of a sequence of smooth wells.

Template Parameters

N	Rank of the array.

◆ energy()

template<size_t N>

array_type::tensor< double, N > GMatElastoPlasticQPot::Cartesian2d::Smooth< N >::energy ( ) const

inlineoverridevirtual

Potential energy per item.

Returns: [shape()].

Reimplemented from GMatElastoPlasticQPot::Cartesian2d::Cusp< N >.

Definition at line 659 of file Cartesian2d.h.

◆ refresh()

template<size_t N>

void GMatElastoPlasticQPot::Cartesian2d::Smooth< N >::refresh ( bool compute_tangent = true )

inlineoverridevirtual

Recompute stress from strain.

From C++, this function need never be called: the API takes care of this.

For Python, this function should only be called when you modify elements of Eps(). For example

mat.Eps[e, q, 0, 1] = value
...
mat.refresh() # "Eps" was changed without "mat" knowing

Instead, if you write an nd-array, the API takes care of the refresh. I.e.

mat.Eps = new_Eps
# no further action needed, "mat" was refreshed

Note though that you can call this function as often as you like, you will only loose time.

Parameters

compute_tangent Irrelevant, ignored.
