1. Critical porosity is estimated in additively manufactured IN718 via crystal plasticity.
2. Porosity is characterized using high resolution tomography.
3. Non-local damage indicator parameters identify the location of fatigue crack initiation.
4. The critical pore size is 20 μm in IN718 with average grain size of 48 μm.

We have published a paper called "Micromechanical model for prediction of the fatigue limit for unidirectional fibre composites" in Mechanics of Materials. See the link here.
The anomalous propagation of short cracks shows generally exponential fatigue crack growth but the dependence on stress range at high stress levels is not compatible with Paris’ law with exponent m=2. Indeed, some authors have shown that the standard uncracked SN curve is obtained mostly from short crack propagation, assuming that the crack size a increases with the number of cycles N as da/dN=H\Delta\sigma^h where h is close to the exponent of the Basquin’s power law SN curve.
In the aerospace industry, testing is critical in successful product development and implementation. Mechanical testing of materials and products used in aerospace applications is governed by strict standards and often require accreditation. The type of testing performed includes tensile, compressive, flexural, fatigue testing, and more.
Dear Colleagues,
The SEM 2019 annual conference abstract deadline has been extended to October 24, 2018. Please see the Call for Abstracts below and consider submitting an abstract.
We invite you to submit a paper to the 2019 Society for Experimental Mechanics (SEM) Annual Meeting in one of the many sessions in the Fatigue and Fracture Track. See below for further information on these sessions, and please forward this to others who may be interested.
The use of 3D printed metal structures is taking a very fast ramp-up in industry. General Electric has demonstrated the possibility of printing titanium fuel injectors for their LEAP engine, EADS has printed a nacelle hinge bracket for the Airbus A320, Boeing is printing plastic inlet ducts for high-altitude aircrafts, hip implants and other prosthetics are exploiting the design freedom of additive manufacturing (AM),...
