“…and decreased with decreasing the moisture contents as rupture force. Similar trends were also observed by Yılmaz (2007) for chestnut varieties, Sharifian & Derafshi (2008) for walnut, Güner et al (1999) for apricot stone, Güner et al (2003) for hazelnut, Oloso & Clarke (1993) for cashew nut and Altuntaş & Yıldız (2007) for faba bean grain. The rupture energy along the X axis was the greatest for Altınay (0.63-1.46 J) followed by Albayrak (0.33-1.44 J), 554-14 (0.33-1.03 J) and Ünal (0.38-0.81 J).…”

“…So far many studies have been conducted on physical and mechanical properties of hard shelled nuts and kernels as hazelnut, pistachio nut, apricot, pine nut, almond, walnut, macadamia nut and cashew nut by Oloso & Clarke (1993), Liu et al (1999), Borghei et al (2000), Aydın (2002), Gezer & Dikilitaş (2002), Aydın (2003), Güner et al (2003), Vursavuş & Özgüven (2004), Vursavuş & Özgüven (2005), Aktaş et al (2007), Arslan & Vursavuş (2008) and Galedar (2009). There are also a few studies on physico-mechanical properties of chestnut.…”

The mechanical properties of four varieties of chestnut (namely; Albayrak, Altınay, Ünal and 554-14) were determined in terms of average rupture force, deformation, rupture energy and firmness. Samples at various moisture contents were compressed by parallel plate along the X, Y and Z axes. Physical characteristics of the chestnut such as dimensions, geometric mean diameter, sphericity, volume and surface area were determined. The results showed that the rupture force, deformation and rupture energy values generally increase with increasing moisture content. The differences in firmness with moisture content are not statistically significant in the all orientations. The maximum rupture energy values at all moisture levels as well as all varieties were obtained for chestnut loaded along either the X or Y axes. The results of the experiments indicated that, the lowest rupture energy value to split the shell of nuts was required along the Z axis. 338enerjisi değerleri tüm nem içeriklerinde ve tüm çeşitler için X veya Y eksenlerinde ortaya çıkmaktadır. Deneme sonuçları kestane kabuğunun yırtılması için en düşük enerji değerine Z ekseninde ihtiyaç duyulduğunu göstermiştir.

“…Besides, in Iran there are also some parts with soil and climatic conditions appropriate for Lima bean production. Today, much data have been published on the physical behaviours of nuts (Akinoso, 2011;Guner et al, 2003;Guzel et al, 2007), grains and seeds (Esehaghbeygi, 2010;Ilori et al, 2011;Legrand et al, 2007). However there is not detailed information on the physical and mechanical properties of Christmas Lima bean.…”

A b s t r a c t. Some moisture-dependent physical properties of Christmas Lima were investigated. Results of experiments on rewetted Christmas Lima bean seed showed increasing in length, width, thickness, geometric mean diameter, volume, sphericity, mass, 1 000 seeds mass, projected area and terminal velocity. A decreasing trend for bulk density and true density was observed. Both static and dynamic coefficients of friction increased as the moisture content increased. The highest static (0.59) and dynamic coefficients of friction (0.34) were found on the rubber surface. The average rupture force, rupture deformation and rupture energy were investigated under compression loading. These characteristics were determined as functions of moisture content, compression orientations and deformation rates. At all deformation rates, rupture deformation and rupture energy of the Christmas Lima bean generally increased with increase of moisture content. Moreover, rupture force decreased for compression along the X-and Y-axis.K e y w o r d s: Christmas Lima bean, moisture content, physical properties

“…Mechanical behaviour of the palm oil seeds (Elaeis guineensis L.) (Raji, Favier 2004) under compression loading is very similar to mechanical behaviour of jatropha seeds and similar to even distribution of strain fields (Owolarafe et al 2007). Deformation characteristics of hazelnut (Corylus avellana L.), macadamia nut (Macadamia integrifolia L.) (Braga et al 1999) or black pepper (Piper nigrum L.) (Murthy, Bhattacharya 1998) are also similar to jatropha deformation characteristic, only the middle part of the characteristics can be substituted by straight line dependence (Güner et al 2003). Deformation characteristics of apricot seeds (Prumus armeniaca L.) and faba bean seeds (Vicia faba L.) can be generally described by the higher degree polynomial function (Lysiak, Laskowski 2004;Vursavus, Ozguven 2004).…”

Herák D., Kabutey A., Sedláček A., Gűrdil G., 2011. Tangent curve utilization for description of mechanical behaviour of pressed mixture. Res. Agr. Eng., This article is focused on the utilization of tangent curve for description of mechanical behaviour of pressed mixture under compression loading. The aim of this experiment was to determine the general equation describing deformation characteristics of pressed mixtures under compression loading and to verify this equation. The experiment was carried out using mixture of seeds of common sunflower (Heliantus annuus L.), jatropha ( Jatropha curcas L.), garden pea (Pisum sativum L.), common bean (Phaseolus vulgaris L.), and also mixture of spruce wood chips and waste paper chips. The results from the experiment showed that mechanical behaviour of the pressed mixtures under compression loading can be described by tangent curve function. From the determined coefficients of determination R 2 it was clear that fitted tangent curve functions described the measured amounts exactly for all pressed mixtures. It can be therefore assumed that this tangent curve function is appropriate for use in pressing any pressed mixtures during linear compression.
