Abstract

Stress-strain state of cutting wedge models is evaluated by photomechanics method in the work. Models are made of optically sensitive organic glass of ED-6 grade. The aim of the study is to improve the method of selecting geometric parameters of the cutting wedge based on experimental data from photomechanics. The effect of the face angle on the strength of the cutting wedge was considered.

Highlights

  • Polarization-optical method of stress analysis is used to simulate the stress state of structures and constructions [1]

  • The photomechanics method complements analytical calculation methods, which are characterized by the high complexity of setting boundary conditions and taking into account all load factors

  • The main purpose of the experiments was to study the strength of the cutting wedge from the value of the face angle

Summary

Introduction

Polarization-optical method (photomechanics method) of stress analysis is used to simulate the stress state of structures and constructions [1]. The main purpose of the experiments was to study the strength of the cutting wedge from the value of the face angle. Two models of a cutting wedge with different face angles were made: negative γ = -15° and positive γ = +15°.
