TOPOLOGICAL OPTIMIZATION OF THE TEST SPECIMEN FOR BIAXIAL TENSION

Problems of Strength and Plasticity, 2019
Applying the approaches of topology optimization, we consider the problem of substantiation of the configuration of the 2D test specimen, in the workspace of which the biaxial stress-strain state is realized. The original area occupied by the specimen is a square plate with a given side size made of an isotropic material.

Optimizing Specimen Quality in Percutaneous Image-Guided Biopsies

This paper examines the critical role of specimen quality in percutaneous image-guidedbiopsies, particularly focusing on the minimization of crush artifact, fragmentation, andcellular disruption. Traditional side notch biopsy devices and their association with crushartifact are evaluated, addressing how this impacts cancer typing accuracy. Furthermore,
