Mixed-mode evaluation of ductile adhesive joints by the single-leg bending test

1st Virtual European Conference on FractureIn the design of adhesive structures, it is extremely important to accurately predict their strength and fracture properties (critical strain energy release rate in tension, GIC, and shear, GIIC). In most cases, the loads occur in mixed-mode (tension plus shear). Thus, it is of great importance the perception of fracture in these conditions, namely of the strain energy release rates in tension, GI, and shear, GII, relative to different crack propagation criteria or fracture envelopes. This comparison allows to determine the most suitable energetic propagation criterion to be used in cohesive zone models (CZM). The main objective of this work is to verify, by CZM, which is the power law parameter (α) that best suits the energetic crack propagation criterion for CZM modelling, using single-lap joints (SLJ) and double-lap joints (DLJ) with aluminium adherends and bonded with a ductile adhesive. With this purpose, numerical simulations of the SLJ and DLJ are carried out, and the maximum load (Pm) is compared with experiments. For the tested materials and geometries, the energetic criterion resulting from the experimental work provided matching numerical results and, thus, the fracture envelope was validated.info:eu-repo/semantics/publishedVersio

The Static Failure of Adhesively Bonded Metal Laminate Structures: A Cohesive Zone Approach

Data on distribution, ecology, biomass, recruitment, growth, mortality and productivity of the West African bloody cockle Anadara senilis were collected at the Banc d'Aguuin, Mauritania, in early 1985 and 1986. Ash-free dry weight appeared to be correlated best with shell height. A. senilis was abundant on the tidal flats of landlocked coastal bays, but nearly absent on the tidal flats bordering the open sea. The average biomass for the entire area of tidal flats was estimated at 5.5 g·m−2 ash-free dry weight. The A. senilis population appeared to consist mainly of 10 to 20-year-old individuals, showing a very slow growth and a production: biomass ratio of about 0.02 y−1. Recruitment appeared negligible and mortality was estimated to be about 10% per year. Oystercatchers (Haematopus ostralegus), the gastropod Cymbium cymbium and unknown fish species were responsible for a large share of this. The distinction of annual growth marks permitted the assessment of year-class strength, which appeared to be correlated with the average discharge of the river Senegal. This may be explained by assuming that year-class strength and river discharge both are correlated with rainfall at the Banc d'Arguin.

Application of the missionary spirituality of Blessed Arnold Janssen, SVD to the activities of the SVD League of Friends

The emergence of the SVD-League of Friends, and the identity of the association, participation and application of the missionary spirituality of Blessed Arnold Janssen by the SVD-League of Friends are explored in this research.There were two methods of research. These were the exploratory method and the participant observation method. Content analysis was used. The major contribution of this research work was that it served as another model of empowerment among the laity in the contemporary Philippine Church.The SVD-League of Friends is an association where members live or witness the three essential components of the missionary spirituality of the Blessed Arnold Janssen. The activities of the association integrate the three components, namely: (1) sacrifice, (2) dialogue, and (3) service.The members of the SVD-League of Friends are individuals who think and pursue. They are people who feel the sacrifice by having the emotions of joy, fulfillment, love, and enjoyment despite their sacrifices in the association. The members apply to their activities the missionary spirituality of Blessed Arnold Janssen.The organizational life cycle was applied to the SVD-League of Friends by including the Foundation and Expansion periods in the analysis of its emergence. The continuity for the emergence of the SVD-League of Friends came about when the core group took the initiative to dialogue with the Provincial Superior

A study of the decreasing enrollment at the Liceo de Masbate High School

v. 2. After reading the letter of the college seminarians, Bishop Bolano stood up and looked through the window of his office towards the direction of the big status of Our Lady of Seven Sorrows, the patroness of the diocese. As he tried to look at the face of Blessed Mother, he suddenly felt at that moment extreme sadness. Not the sadness of remembering the seven sorrows that pierced the heart of Mary, while she was still on earth, but the sadness of indecision. This is due at this time when the very heart of the diocese, the seminary, was being pierced by two of his promising priests, being accused of homosexual activities with the seminarians
