Operator POST_ELEM

1 Goal

To calculate quantities on whole or part of the structure. The calculated quantities correspond to
particular options of calculation of affected modeling.

The currently available options are:

·
calculation of the mass, inertias and the position of the center of gravity,
·
calculation of the potential energy,
·
calculation of the kinetic energy,
·
calculation of the work of the external efforts,
·
calculation of the indicators of loss of proportionality of the loading in elastoplasticity,
·
calculation of the limiting load,
·
calculation of the constraint of Weibull,
·
calculation of the growth rate of a spherical cavity (Rice - Tracey),
·
calculation of elastic energy and total energy,
·
calculation of the surface of a hole in a grid 2D.

WEIBULL

3.14.1 Drank

Key word allowing for each defined moment, the calculation of the elementary field of the power

count plastic deformation, by:

m (

ref.
V
Kp

K p indicates the part of the mesh K which plasticized, i.e., the part of K where deformation
p
figure cumulated exceeds a certain threshold; 1 accounts for the maximum principal constraint and 1
represent the maximum principal plastic deformation.

The parameters material m, Vref and the threshold of plasticity are defined in DEFI_MATERIAU by
relation of behavior WEIBULL (cf [R7.02.06]).

Once determined this elementary field, the option calculates by “summation” the constraint of Weibull
of a field D for each definite moment:

1

m
(D) = C m (K)
W
W

K D



where C is a coefficient intended for the taking into account of symmetries (case Bi and three-dimensional) and of
the thickness (in the two-dimensional case) of the structure containing the field D (key word
COEF_MULT).

The probability of rupture of the field D is then calculated by:

m

P (D) = 1 - Exp
W


W
-

Mr.


U
The parameter “forced of cleavage” µ is, him also, defined in the relation of behavior
WEIBULL.

Lastly, the preceding expressions of the constraint of Weibull and the probability of rupture are not
valid that in the case of a monotonous way of loading. This type of postprocessing can
nevertheless also to be applied to a way of more general loading, including when the constraint
on cleavage depends on the temperature (relation of behavior WEIBULL_FO). Expressions of
forced of Weibull and the probability of rupture are then different (cf [R7.02.06]).

Note:

For the key word factor WEIBULL, the model and the field of material are obligatory.

INDIC_ENER

3.16.1 Drank

Key word factor allowing to calculate a total indicator of loss of proportionality of the loading
in elastoplasticity, founded on the density of energy. This indicator is described in detail in the document
[R4.20.01].
One points out his function and his expression. This indicator is intended to detect if during
history of the structure and until the current moment T, and for a zone of the structure chosen by
modelisator, there was loss of proportionality of the loading (i.e it acts to have a total measurement
change of the principal directions of the tensor of constraints for each point of the zone
defined by the user).
This indicator is usable only for models whose material presents a work hardening
isotropic and whose elements are isoparametric 2D or 3D.
This indicator has as an expression:

1

I =
1 -
FD


V v


where:

·
V is the volume of the field defined by the user,
·
is the density of total elastic energy associated the traction diagram if one
considered the non-linear elastic material.

INDIC_SEUIL

3.17.1 Drank

Key word factor allowing to calculate a total indicator of loss of proportionality of the loading
in elastoplasticity.
This indicator makes it possible on the one hand to know, on average about the zone considered, if the tensor of
constraints and that of the plastic deformations have the same directions and if the plastic threshold is
reached at the current moment, and in addition if during the history the plastic deformation changed
direction.
This indicator has as an expression:

p

.
I =

FD


V v
R

(p). p

where:

·
V is the volume of the field defined by the user,
·
is the tensor of the constraints at the moment running,
·
p is the tensor of the plastic deformations at the moment running,
·
R (p) is related to work hardening (with R (O) = there where is the limit there
of elasticity).
i.e. it is the threshold of the traction diagram associated with the cumulated plastic deformation
p.
·
p is the cumulated plastic deformation.

Note:

If one has (
R p). p = 0, one poses I = 0.

The scalar product. p is associated the standard within the meaning of von Mises.
This indicator is standardized and has a value ranging between 0 and 1.
It is null if the loading preserved its character proportional in each point of V all to length
past history.
This indicator is described in detail in the document [R4.20.01].

CHAR_LIMITE

3.18.1 Drank

Post_traitement of the calculation of the limiting load [R7.07.01 §2.3].
This key word factor allows the calculation of the limiting load of a structure by a kinematic approach.
Its employment requires as a preliminary to have carried out a nonlinear calculation (see operator
STAT_NON_LINE [U4.51.03]) indicated by the key word RESULTAT and whose characteristics are them
following:

·
law of behavior NORTON_HOFF,
·
increasing list of moments of calculation corresponding to values of regularization of the law of
NORTON_HOFF which tends towards 1 (in practice, one recommends to be limited to moments
ranging between 1 and 2 which does not lead to too long calculations while allowing
to obtain an upper limit of the load limits sufficiently precise),
·
loading (unit) controlled corresponding to the loading by report/ratio to which one seeks with
to consider the limiting load, the method of control being TYPE = “ANA_LIM”,
·
possibly a constant loading whose it is then necessary imperatively to point out the existence
by the key word CHAR_CSTE = “OUI”.

Operator POST_ELEM then produces a table which gives for each moment of calculation, i.e.
for increasingly weak regularizations, a limit upper CHAR_LIMI_SUP of the load
limit supported by the structure. Moreover, in the absence of constant loading, CHAR_CSTE =
“NON”, the table also contains an estimate CHAR_LIMI_ESTIM of a lower limit of
charge limit. On the other hand, if a constant loading is present, CHAR_CSTE = “OUI”, such
estimate of the lower limit is not available any more but the table contains the power then
PUIS_CHAR_CSTE of the constant loading in the field speed solution of the problem.
A detailed example of calculation of limiting load is provided in [U2.05.04].

Calculation is carried out on the basis of SD result, well informed under key word RESULTAT, for
which nodal forces, i.e. the interior forces, were calculated beforehand by
the operator CALC_ELEM, option “FORC_NODA” [U4.81.01]. In the case of real work, the initial moment T
0
corresponds to the first moment filed in the SD result (taking guard with the fact that the initial state is not
not filed automatically, to see key word ARCH_ETAT_INIT of operator STAT_NON_LINE
[U4.51.03]); integration in time is carried out by a method of trapezoids. Two sizes
TRAV_REEL and TRAV_ELAS are calculated for each moment filed in the SD result.
These quantities can be interpreted graphically on the response curve forces ­ displacement of
the structure (provided that the force is dual displacement, for example pressure and volume
in the case of a cavity under pressure).
