Целью изобретени   вл етс  повышение точности и расширение технологических возможностей способа. Изготавливают партию образцов с Исследуемым концентратором напр жений. Образцы последовательно закрепл ют кон- сольно и нагружают до разрушени , при этом рассто ние от места креплени  до концентратора увеличивают от -нул  до значени , при котором образец разрушитс  в месте креплени . Значение теоретического коэффициента концентрации напр жений определ ют из услови  равенства максимальных напр жений в сечении с концентратором и в сечении у места креплени .The invention relates to a testing technique and can be used to examine the properties of samples. The aim of the invention is to improve the accuracy and expand the technological capabilities of the method. A batch of samples is made with the Investigated Stress Concentrator. The samples are successively secured with a cantilever and loaded to failure, while the distance from the attachment point to the concentrator is increased from the bottom to the value at which the sample is destroyed at the attachment point. The value of the theoretical stress concentration coefficient is determined from the condition of equality of the maximum stresses in the cross section with the concentrator and in the cross section at the attachment point.

Description

Изобретение относитс  к испытательной технике и может быть использовано при исследовании прочностных свойств твердых материалов.The invention relates to a testing technique and can be used in the study of the strength properties of solid materials.

Цель изобретени  - повышение точности и расширение технологических возможностей способа путем улучшени  технологии испытаний.The purpose of the invention is to improve the accuracy and expand the technological capabilities of the method by improving the test technology.

Способ определени  теоретического коэффициента концентрации напр жений заключаетс  в следующем.The method for determining the theoretical stress concentration factor is as follows.

Изготавливают партию образцов с исследуемым концентратором напр жений . Образцы последовательно закрепл ют консольно и нагружают до разрушени , при этом рассто ние от места креплени  до концентратора увеличивают от нул  до значени , при котором образец разрушитс  в месте креплени . Значение теоретического коэффициента концентрации напр жений определ ют из услови  равенства максимальных напр жений в сечении с концентратором ив сечении у места креплени .A batch of samples is made with the stress concentrator under study. The samples are successively fixed in a cantilever manner and loaded to failure, while the distance from the attachment point to the concentrator is increased from zero to the value at which the sample is destroyed at the attachment point. The value of the theoretical stress concentration coefficient is determined from the condition of equality of the maximum stresses in the cross section with the concentrator and in the section at the attachment point.
