Uniaxial tensile testing of micro-samples Micro-specimen tensile testing requires reliable optical measurements at very small gauge lengths. By limiting the effect of slight out-of-plane movements on magnification, the ST semitelecentric extensometer helps maintain accurate strain and displacement readings throughout the test. The ST system’s adjustable field of view (FoV) makes efficient use of camera resolution

Thermo-mechanical fatigue testing of miniature specimens Thermo-mechanical fatigue (TMF) testing evaluates material behavior under simultaneous cyclic mechanical loading and changing temperatures. It is used to assess fatigue life, cyclic stress–strain response, hysteresis behavior, and damage development under conditions that closely represent demanding real-world service environments.Three main damage mechanisms contribute to thermo-mechanical fatigue: The tests were

MATERIAL PROPERTIES CONTROL of 3d printed components Defining quality in additive technologies requires consideration of the high variability of material properties, print settings, post-processing and environmental conditions, all of which can influence the final behaviour of printed parts. Therefore, quality assessment should not rely only on manufacturer datasheets or on basic visual and dimensional inspection.

The helmet drop test – high speed camera During the helmet drop test, it is essential to determine the impact velocity. Also, the behavior of the helmet after impact can be analyzed. Measuring the impact velocity using the DIC method is more convenient than numerical integration acceleration from accelerometers. The experimental setup consists of a

HIGH-PRECISION ANALYSIS OF BOOT DOOR MOTION To evaluate the kinematic behaviour, oscillations and deformation of the car boot mechanism during the closing sequence, a dynamic measurement campaign was conducted using a 3D Digital Image Correlation (DIC) system. A large speckle-patterned calibration cloth was first employed to quickly establish an accurate stereo-camera calibration across the required

Determining Forming limit curves using DIC KEYWORDS TEST SET-UP OUTPUT Specimens and Measurement setup Before measurement, a set of metallic sheet specimens made from DR 520 CA with a nominal thickness of 0.2 mm wasprepared. The aim was to generate various stress states during the Nakajima-type forming test. To achieve this,geometrically distinct specimens were designed

The Line probe was used to measure strain or length change in the specified direction. Intelligent features allow for precise setup of gauge length and aligning the Line probe

Analysis of Spruce wood Deformation During Compression Testing KEYWORDS TEST SET-UP OUTPUT Inspection and evaluation It was observed that wood exhibits anisotropic behaviour, deforming differently along various directions. To accurately capture local deformations, the evaluation region in the 3D video extensometer with post-processing software was configured so that two sides of the specimen are visible.

Once the IR camera and Alpha DIC software, a crucial component of our measurement setup, were connected and the systems were calibrated, the test could begin. The DIC camera and the Alpha DIC software played
