Stress analysis      TRI/3D-FEM
Using a bone model reconstructed from CT images with TRI/3D, bone stress analysis
such as compression test and bending test is performed.
Different physical property values are given to cortical bone and cancellous bone,
and fracture under forced displacement can be simulated.


   Large-scale data analysis   
Automatic generation of cancellous bone and cortical bone mesh.
Several million meshes can be run on a 64-bit computer.

Since the analysis is performed using the overall image of the actual model,
You can grasp the mechanical dependence between parts at a glance.
From model creation to solver execution and evaluation of analysis results,
it is possible with simple operations.

The entire RAT femur can be subjected to stress analysis with cancellous bone attached.

   Shear stress analysis   
Correlation of MDCT model with ƒÊCT model
Shear stress analysis values ??using the MDCT image model are correlated
with ƒÊCT image model analysis values.
The stress distribution matches.
