ABOUT US

We are providing high quality services in the field of scientific researches (biomechanics, solid mechanics, continuum mechanics), finite element analysis and engineering automation. Using of generic approaches give us possibility to apply our knowledge in different branches of industries. Our creative team of scientists and engineers are able to solve the problems of any level of difficulty.

SERVICES

The list of services below is the main one but not limited.

 

CAD system automation

Nowadays design engineering goes on the way of process automation. This approach gives
possibility to engineer concentrate directly on the creative process and avoid routine work.
A number of actions can be automate in any CAD system starting with modelling of simple
units and finishing with huge assemblies, generating outputs, perform necessary calculations,
optimization, etc.

Our company works with the best CAD software available. We have experience of creating
special tools and add-ins (additional information available through the request) for a wide
range of CAD packages.

 

Finite Element Analysis

Develop a safe and reliable design without proper calculations almost not possible.
Taking into account that modern constructions is quite complex the one of the best
tools to analyze them is a finite element method (FEM). We can cover most branches
of physics and able to do following calculations:

  • Mechanical calculations (stress and strain state, modal, thermal,
    buckling analysis, etc.)
  • Computational Fluid Dynamics (CFD)
  • Electromagnetics calculations
  • Multiphysics calculations
  • Biomechanical calculations
  • APDL programming

 

Research

The scientific research is the best way to understand new structures and processes more deeply. One of the best tools for making these investigations is mathematical modelling. The new mathematical model, which are developed and verified, can not only give you information about a particular case but it also can be the core of your own future special software. The scientific approach is especially important in the multidisciplinary areas such as  biomechanics for example. A number of projects have been done by our group in different fields of biomechanics, such as dental biomechanics, traumatology, otolaryngology.

During finite element modeling usually the necessary information for geometry creation is obtained from the MRI data. We are developing our own algorithms for creation of 3D solid model based on  the medicine images.

BIOMECHANICS

Mathematical modelling and numerical methods are widely used nowadays to make treatment more effective. These approaches are also used to optimize the implants and to improve efficiency of orthodontic devices. Our team have years of experience in different branches of biomechanics and biomedicine. The main problems which have been solved are listed below but not limited.

 

Dental biomechanics

Both mathematical and finite element models are developed for the orthodontic appliances employed for treatment of the dental anomalies and maxillofacial defects. Periodontal ligament behavior has been simulated. Based on analytical and finite-element models tooth root movements are defined. In addition, the locations of the tooth root resistance centers for different symmetry cases are obtained. Complex models taking into account the bone structures of the human skull, teeth and periodontal ligament are also considered. Tooth implant modelling and its finite-element optimization have also been performed.

 

Surgery and Traumatology

To remove the tumor and metastatic lesions of the long bones (femur, tibia, shoulder and forearm) surgical resection is used. After this operation, a rectangular bone defect is formed. Mechanical properties of bone are reduced significantly and there is a high risk of pathological fracture in the area of bone defect. To predict the ultimate load during routine human activity the finite element analysis is performed. Based on these results recommendations on postoperative rehabilitation of the patient is formulated to avoid the occurrence of a pathological fracture. These guidelines also provide the opportunity to avoid excessive treatment and improve the patient's quality of life.

 

Otolaryngology

The middle ear is one of the components of the human hearing system. Its main function is to transfer sound waves to the inner ear through the eardrum vibrations. Pathological changes in the eardrum lead to reduced hearing conduction and significantly degrade the quality of life. To eliminate diseases of the tympanic membrane a cartilage graft is imposed to the surface with the pathological changes. To predict the thickness of the cartilage graft in various pathological changes in the tympanic membrane finite element and mathematical modeling was performed. Based on these results recommendations for surgical operations on the tympanic membrane are formulated.
