On Some Problems in Determining Tensile Parameters of Concrete Model from Size Effect Tests

open access: yesPolish Maritime Research, 2019
The paper presents results of numerical simulations of size effect phenomenon in concrete specimens. The behaviour of in-plane geometrically similar notched and unnotched beams under three-point bending is investigated.

Coniform-shape tool for splitting of wooden logs

open access: yesResearch in Agricultural Engineering, 2015
The article deals with design of a coniform tool with rotary motion for splitting of logs. The tool is proposed using a fracture mechanics theory. The approach of energy balance during crack growth in a split wood log is applied for construction design ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

open access: yesAdvanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

DETERMINATION OF THE FRACTURE ENERGY AND THE FRACTURE RESISTANCE OF INTERFACES

open access: yesLe Journal de Physique Colloques, 1985
The basic concept and the fracture mechanics methods for determination of the fracture energy and the fracture resistance of interfaces between semi-brittle materials are reviewed. The interfacial fracture energy is derived from the global energy balance concept for crack propagations in an interface, whereas the fracture resistance parameter is based ...
