Software and analysis tools implementing peridynamic theory

about us

GLOBAL ENGINEERING RESEARCH AND DEVELOPMENT (GERT) IS A START-UP COMPANY FOCUSING ON THE DEVELOPMENT OF STATE-OF-THE-ART ANALYSIS SOFTWARE TOOLS. 

 

THESE TOOLS ARE APPLICABLE TO DIVERSE ENGINEERING FIELDS, RANGING FROM FAILURE PREDICTION IN STRUCTURAL AND ELECTRONIC MATERIALS TO MEDICAL IMAGING, IMAGE RECONSTRUCTION AND DATA MANIPULATION.

 

THE SOFTWARE ALGORITHMS ARE BASED ON A RANGE OF METHODS INCLUDING FINITE ELEMENTS AND PERIDYNAMICS 

PERIDYNAMICS IS A NONLOCAL APPROACH.
 

  • IT PROVIDES THE SOLUTION OF DIFFERENTIAL AND INTEGRAL EQUATIONS IN A UNIFIED MANNER REGARDLESS OF THEIR INTRINSIC BEHAVIOR AND PRESENCE OF SINGULARITY.
     

  • IN THE CONTEXT OF SOLID MECHANICS, IT CONSIDERS THE SAME EQUATIONS OF A DEFORMING STRUCTURE WITH OR WITHOUT DISCONTINUITIES. 
     

  • IT REMOVES THE NEED FOR THE SPECIAL TECHNIQUES OF FRACTURE MECHANICS FOR DAMAGE INITIATION AND PROPAGATION. 
     

  • THERE IS NO NEED FOR EXTERNALLY APPLIED CRITERIA FOR CRACK PROPAGATION.
     

  • IT PERMITS ARBITRARY AND COMPLEX CRACK PROPAGATION PATHS.

 

  • FEA IS ROBUST IN PARTICULAR FOR DETERMINING STRESS FIELDS IN COMPLEX STRUCTURAL COMPONENTS UNDER GENERAL LOADING CONDITIONS.
     
  • FEA MAY NOT BE VERY SUITABLE FOR DAMAGE AND FRACTURE MODELING BECAUSE IT REQUIRES SPECIAL CONSIDERATIONS AND TREATMENT.

  • ANALYSIS OF DISCRETE DATA SUCH AS INTERPOLATION, REGRESSION, RECOVERY, AND SMOOTHING.
     
  • SOLUTION OF NONLINEAR ORDINARY DIFFERENTIAL EQUATIONS WITH INITIAL OR BOUNDARY VALUES.  
     
  • SOLUTION OF LINEAR AND NONLINEAR PARTIAL DIFFERENTIAL EQUATIONS (PDE) OF PARABOLIC, HYPERBOLIC AND ELLIPTIC TYPE WITH AND WITHOUT A DISCONTINUITY IN THE FORM OF AN INTERFACE OR A CRACK.  
     
  • SOLUTION OF COUPLED FIELD PDES DESCRIBING DIFFUSION, DEFORMATION, FLUID FLOW, NONLINEAR ACOUSTICS, GAS DYNAMICS AND TRAFFIC FLOW.
     
  • SOLUTION OF INTEGRO-DIFFERENTIAL EQUATIONS BY EMPLOYING THE VARIATIONAL ITERATION METHOD (VIM). 

      RECOVERY OF MISSING DATA
 

      DATA COMPRESSION 
 

      DATA MANIPULATION

AS A PROOF-OF-CONCEPT, THE IMAGE ANALYSIS TOOL CAN BE USED TO FILL IN ANY MASKED PART OF AN IMAGE, ALLOWING FOR VARIOUS APPLICATIONS, SUCH AS COMPRESSION, RECOVERY, HEALING BRUSH, DESPECKLE, SCALING, AND MORE.

THIS APPROACH HAS BEEN APPLIED TO LOSSY IMAGE COMPRESSION, MRI DATA RECOVERY (REDUCED SCAN TIME), AND MANY OTHER APPLICATIONS.  IMAGES HAVE BEEN ACCURATELY RECOVERED FROM ONLY 15% OF THE ORIGINAL DATA (85% MISSING DATA), AND CAN BE ACCURATELY APPROXIMATED FROM LESS.
