Detailed Description

compute stress tensors given point load on semi-infinite domain.

Date:
2001/10/11 13:37:56
Revision:
1.33

vtkPointLoad is a source object that computes stress tensors on a volume. The tensors are computed from the application of a point load on a semi-infinite domain. (The analytical results are adapted from Saada - see text.) It also is possible to compute effective stress scalars if desired. This object serves as a specialized data generator for some of the examples in the text.

Member Function Documentation

virtual const char* vtkPointLoad::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStructuredPointsSource.

int vtkPointLoad::IsTypeOf const char *    type [static]
 

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStructuredPointsSource.

virtual int vtkPointLoad::IsA const char *    type [virtual]
 

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStructuredPointsSource.

vtkPointLoad* vtkPointLoad::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkStructuredPointsSource.

void vtkPointLoad::PrintSelf ostream &    os,
vtkIndent    indent
[virtual]
 

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkSource.

vtkPointLoad* vtkPointLoad::New   [static]
 

Construct with ModelBounds=(-1,1,-1,1,-1,1), SampleDimensions=(50,50,50), and LoadValue = 1.

Reimplemented from vtkStructuredPointsSource.

virtual void vtkPointLoad::SetLoadValue float    [virtual]
 

Set/Get value of applied load.

virtual float vtkPointLoad::GetLoadValue   [virtual]
 

Set/Get value of applied load.

void vtkPointLoad::SetSampleDimensions int    i,
int    j,
int    k
 

Specify the dimensions of the volume. A stress tensor will be computed for each point in the volume.

void vtkPointLoad::SetSampleDimensions int    dim[3]
 

Specify the dimensions of the volume. A stress tensor will be computed for each point in the volume.

virtual int* vtkPointLoad::GetSampleDimensions   [virtual]
 

Specify the dimensions of the volume. A stress tensor will be computed for each point in the volume.

virtual void vtkPointLoad::GetSampleDimensions int    data[3] [virtual]
 

Specify the dimensions of the volume. A stress tensor will be computed for each point in the volume.

Specify the region in space over which the tensors are computed. The point load is assumed to be applied at top center of the volume.

virtual void vtkPointLoad::SetModelBounds float   [6] [virtual]
 

Specify the region in space over which the tensors are computed. The point load is assumed to be applied at top center of the volume.

virtual float* vtkPointLoad::GetModelBounds   [virtual]
 

Specify the region in space over which the tensors are computed. The point load is assumed to be applied at top center of the volume.

virtual void vtkPointLoad::GetModelBounds float    data[6] [virtual]
 

Specify the region in space over which the tensors are computed. The point load is assumed to be applied at top center of the volume.

virtual void vtkPointLoad::SetPoissonsRatio float    [virtual]
 

Set/Get Poisson's ratio.

virtual float vtkPointLoad::GetPoissonsRatio   [virtual]
 

Set/Get Poisson's ratio.

virtual void vtkPointLoad::SetComputeEffectiveStress int    [virtual]
 

Turn on/off computation of effective stress scalar.

virtual int vtkPointLoad::GetComputeEffectiveStress   [virtual]
 

Turn on/off computation of effective stress scalar.

virtual void vtkPointLoad::ComputeEffectiveStressOn   [virtual]
 

Turn on/off computation of effective stress scalar.
